Comment(by michaelld@…):

 Per ticket #25320, I'm updating qt4-mac (and the various qt4-foo variants)
 to use the select group, and also to correctly use compiler.cpath and
 compiler.library_path instead of -I.  Further, ${prefix}/include will be
 the last searched path, so hopefully some of the 'conflicts' found here
 will be resolved.  In my initial testing,  libevent no longer conflicts
 during build.  I don't have the other conflicting ports installed right
 now, so I cannot vouch that my changes work for them (but, I will try to
 try them too).

 Give me a bit to sort out the qt4-foo Portfile changes, try the upgrade,
 and if it still doesn't work then post back here & I'll try to fix it.  If
 upgrading does work at that time, then IMHO we can close this ticket.
