Comment:

 Yes, the github portgroup (which this port should be using anyway) lets
 you get a tarball from any commit. But version 0.8.3 was released in 2008.
 Pulling the latest code from 2014 would bring in years of changes, in
 addition to this tcl fix. I would rather not do that. If the developer
 feels it's ready for release, the developer should tag a release, and then
 we can update the port to that release. Until then, we should probably
 just backport the specific fixes that are needed to fix the problem at
 hand.
