Comment (by kencu):

 I think you should undo all those symlinks you put in to the newer tools,
 and try to get your 10.6 systems back to virginal state. Then try
 rebuilding mysql57.

 Having those symlinks can work around a problem sometimes for a single
 build, but leaving them there all the time causes unknown effects on the
 build system that we simply can't work around.

 If we put the {{{/usr/bin/libtool -> ${prefix}/bin/libtool}}} fix into the
 ports tree, then the buildbot will build mysql57 and you can just download
 it, which gets you moving again at least. But you should get your system
 into a state where it can build it directly of course, and having a system
 that is as stock as possible is the first, best, way to make sure that you
 can build things.
