+**Installing MacPorts on Ubuntu Linux**
+
+----
+
+MacPorts has been designed to be multi-platform, and it does install on Ubuntu Linux with modest modifications. Please note that at this point in time, this is a highly experimental process, and issues are expected to arise.
+
+First, some quick notes for those familiar with Darwin;   on Ubuntu:
+
+apt is the built-in package manager, similar to "port".
+
+"sudo apt install" is similar to "sudo port install".
+
+"apt info" is similar to "port info"
+
+"apt-file show" does something similar to "port contents", but the software does not have to be installed.
+
+
+To install MacPorts on Ubuntu Linux, you must first install the necessary prerequisites that are typically found on Darwin systems. At the time of writing, this was:
+{{{
+sudo apt install clang-9
+sudo apt install clang
+sudo apt install mtree-netbsd
+sudo apt install tcl8.6
+sudo apt install curl
+sudo apt install sqlite3
+sudo apt install gnustep
+sudo apt install libcurl4-gnutls-dev
+sudo apt install libsqlite3-dev
+sudo apt install libssl-dev
+}}}
+or, all at once:
+{{{
+sudo apt install clang-9 clang mtree-netbsd tcl8.6 curl sqlite3 gnustep libcurl4-gnutls-dev libsqlite3-dev libssl-dev
+}}}
+
+Then download the macports tarball using a web browser from macports.org, perhaps using the included FireFox browser, and decompress it, as per the usual Darwin instructions <https://www.macports.org/install.php#source>. 
+
+I suggest that you don't install startup items at this point in time, as this functionality is different on Ubuntu, so configure your build like this:
+{{{
+./configure --without-startupitems
+}}}
+and then 
+{{{
+make && sudo make install
+}}}
+
+Then add the "macports" user, in the Ubuntu way:
+{{{
+sudo adduser --system --group --home /opt/local/var/macports/home  --disabled-password macports
+sudo chown -R macports:macports /opt/local/var/macports/home
+}}}
+
+Add the macports directory to your PATH as usual, but on Ubuntu, by editing ".bashrc", for example with {{{nano}}}, adding a line like this:
+{{{
+export PATH=/opt/local/bin:/opt/local/sbin:$PATH
+}}}
+
+Also add that PATH to the sudo command's path, like this:
+{{{
+sudo visudo
+}}}
+and add it to the secure_path
+{{{
+Defaults  secure_path="/opt/local/bin:/opt/local/sbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin"
+}}}
+There are some differences between Darwin and Ubuntu, and to work around some of these that are not already compensated for by MacPorts base, set some defaults in {{{macports.conf}}} like this:
+
+{{{
+sudo gedit /opt/local/etc/macports/macports.conf
+}}}
+and add:
+{{{
+buildmakejobs          2                # or a more appropriate number for your processor count
+default_compilers      clang            # compiler selection is not yet working on Ubuntu, this chooses /usr/bin/clang which works best with macport's portfiles
+cxx_stdlib             libstdc++        # configure.cxx_stdlib is not yet working on Ubuntu, this fills in appropriate default
+build_arch             x86_64
+}}}
+
+Darwin and Ubuntu supply 'sed' in different locations, so rather than edit many Portfiles that expect it in the Darwin location, you can do this:
+{{{
+sudo ln -s /bin/sed /usr/bin/sed
+}}}
+
+And at that point, you should be able to run normal MacPorts commands. 
+{{{
+sudo port -v selfupdate
+}}}
+will update your ports tree to the current status.
+
+And then try to install a typical port, like this:
+{{{
+sudo port -v install libffi
+}}}
+
+And presto:
+{{{
+$ port -v installed
+The following ports are currently installed:
+  libffi @3.2.1_0 (active) platform='linux 5' archs='x86_64' date='2020-05-02T23:25:44-0700
+}}}
+
+You can certainly expect to come across issues; MacPorts' PortFiles have largely been written to assume they are installing on Darwin, but with minor modifications to some ports, seem happy with Linux as well.
