Unable to install Erlang on OS X Lion

sudo port install erlang (after a sudo port clean --all erlang) _always_ has issues with the configure phase - Initial message trace:

[Log file attached]

It appears that there's no corresponding erlang*bz2 at packages.macports.org; running port with -D <path to Portfile> also fails the same way.

This is critical to our development and I'd like to see it resolved as soon as is possible, thanks very much for your help!

main.log of 'port install erlang'

However, changing directory to the working directory and running './configure <options>' works, and so does make. What I don't know are the steps needed to push things to destroot and activate the software so that Macports can recognize the package as installed ...

In the future, please fill in the Port field, Cc the port maintainer(s) and use WikiFormatting. Also High priority is reserved for Macports team member use only.

It seems to be having trouble using the compiler on your system. Do you have the Xcode command line tools installed? You might have installed Xcode, but not installed the separate Command line tools package.

The build log shows the following error:

:info:configure checking for gcc... /usr/bin/llvm-gcc-4.2
:info:configure checking for C compiler default output file name... configure: error: C compiler cannot create executables
:info:configure See `config.log' for more details.
:info:configure Command failed:  cd

Does /usr/bin/llvm-gcc-4.2 actually point to anything? If not, you probably just need to install the command line tool set.

Otherwise, please attach the 'config.log' mentioned above so we can see what the error is.

The original reported contacted me to let me know that the issue was that he had not accepted the Xcode license agreement. Once he did so, the build worked as expected.
