How to install an older version of a port
- Audience: Anyone needing an older version of a port than is currently available in the repository
- Requires: MacPorts >=1.7
MacPorts does not include a feature to let you install an older version of a port. It only lets you install the current version of the port that has been created by the port author. You can work around this by getting an older version of the portfile from the Subversion repository.
Step 1: Finding the right revision
To install an older version of the port, you'll have to manually download the files from the repository. Browse the repository to find the directory of the port you want, then use the Revision Log link in the upper right to find the older version that you want to install. For example, if you wanted to install the older 8.4.16 version of tcl, browse to the lang/tcl directory and look at its revision log. Here you'll note that tcl was updated to 8.5.0 in r32235, so you want the revision before that, which was r30810. Click the @30810 link in the revision log (not the  link) to see the directory as it existed in that revision.
Step 2: Getting the Portfile
Click the Portfile to see it, then download it to disk using the Original Format link at the bottom of the page. The tcl port doesn't have a files directory, but if it did, you should download each file within it as well, and place them in a files directory on your disk in the same place where you downloaded the Portfile.
Step 3: Building the downloaded port
Finally, use the Terminal to cd to the directory where you downloaded the Portfile and type "sudo port install".
Alternative method to getting the port
Subversion can be used as well to fetch an older port, and is simpler for one that has a files/ subdirectory.
Step 1: Install Subversion
sudo port install subversion
This step is optional for Mac OS X 10.5 Leopard and later, which already include a Subversion client, but you may want to install it from MacPorts anyway because its version is likely newer than the one included with your operating system.
Step 2: Finding the right revision
Follow Step 1 earlier to find the right revision for the port you need, e.g. r30810.
Step 3: Checking out the port
Using the revision number, port category and port name, check out the port directory at that revision using the svn command:
svn co -r 30810 http://svn.macports.org/repository/macports/trunk/dports/lang/tcl
This creates a tcl directory in your current location, and populates that with everything the port needs to build. Replace "30810" and "lang/tcl" with the correct revision and category/portname for the port you're interested in.
