 everything I tested worked or was at least trivial to fix. I even got
 `cmake` to work, even though I had to manually run a bunch of commands (I
 hope that the upstream will fix the problem soon).

 that comes with the need to switch to gcc), would it be feasible to create
 a semi-official "use-at-your-own-risk" version of MacPorts using `libc++`
 by default and set up a buildbot? Some people say that we don't have the
 manpower to keep two versions around and that just switching to `libc++`
 for everyone can hardly be done.

 I am not so convinced having parallel MacPorts versions, using different
 C++ runtimes, is really worth it. It would just confuse users who
 otherwise don't care about such things, as to which they should use etc.

 Making the switch to build against libc++ by default is easy. The hard bit
 would be how to handle the transistion for users, as they would have to
 have a gull rebuild of their complete MacPorts stack. It would need to be
 done automatically I think. I do agree with you though it might be
 something to consider...
