Great, then you've solved the problem, and there was no bug.
You couldn't uninstall gegl, because an old version of gimp2 which you still had installed depended on it.
The check for broken packages only applies to active ports. rev-upgrade correctly reported that your active port gegl was broken, for whatever reason, but it couldn't be rebuilt because gegl was deliberately removed from the ports tree, because nothing current needed it anymore.
The correct solution was to uninstall gegl and the old gimp2 that depended on it, which you did by running reclaim.
The unsupported compiler warning unfortunately didn't tell us what port it applies to, but since you weren't trying to build a port at the time you can ignore it.
We also have a bug at this time that that message is sometimes displayed when it is not accurate, since a port will sometimes subsequently still build successfully. IIRC this is seen primarily (only?) on 10.8 and earlier systems with ports that use C++11 or later. We should investigate and fix that. But the situation might be different or fixed if we merge the refined compiler selection PR, so we should focus on that first, then retest. https://github.com/macports/macports-base/pull/88
