But, that new version is actually broken (for a completely unrelated reason). So, now I can’t use the new version of the port, and I want to go back to the old version, but I can just activate it, because of the dependent issue. So, I want to just have macports rebuild the old version from source.

Sure. Sorry that my description was not detailed enough.
I have openmodelica-devel installed, and it was working fine. And, I have often done upgrades with no problem.
Some install details are here: https://openmodelica.org/download/download-mac <https://openmodelica.org/download/download-mac>
And, they keep the source code here: http://build.openmodelica.org/apt/pool/contrib/ <http://build.openmodelica.org/apt/pool/contrib/>
Yesterday I upgraded qt4-mac. That caused macports to determine that a few ports were broken (since qt4-mac seems to have changed the location of some files) and to cause them to rebuild. One that it tried to rebuild was openmodelica-devel. The problem is that I was not using the most recent version. They upgrade every few hours typically, as this is develop code. Some recent change that they made has caused the recent versions not to build correctly. The developers are aware of that, and it will get fixed eventually.
So, I just wanted to keep using the version I had from a few days ago. The problem is that macports saw the broken install of openmodelica-devel was not the newest so downloaded the new source and tried to build it, and failed due to the bug mentioned earlier. Now the problem is that if I activate the older version (a few days old) it activates, but doesn’t run (because it linked against the old location of qt4-mac libraries).
So, my current situation is I have old versions installed but not activated. And, I can’t get old ones to work, and I can’t build a new version, since there is a bug that is yet to be fixed in openmodelica.
So, would like to do is to rebuild an old version from the source that was downloaded when I last did a successful upgrade and build. Since that build worked, and left the source stored in macports, it seems like there should be a way to reactivate that version, but let it use the source and rebuild it, instead of just doing the typical activate from the binaries that macports build and saved.
Does that make more sense?
