Comment (by ryandesign):

 Sounds like maybe something replaced your libX11.6.dylib with an older
 version without MacPorts knowing. To fix that specific problem, you could
 force MacPorts to reinstall that port. First, make sure your ports are up
 to date:

 {{{
 sudo port selfupdate
 sudo port upgrade outdated
 }}}

 Then, using `port provides /opt/local/lib/libX11.6.dylib` to discover
 which port provided the file that got replaced, you could then run:

 {{{
 sudo port -n upgrade --force xorg-libX11
 }}}

 However, if xorg-libX11's files got replaced, who knows how many other
 ports' files got replaced. You would have to do the same for those. If you
 can't identify all the files that got replaced that need reinstalling, or
 can't explain how the files got replaced, maybe the safest thing to do is
 to uninstall MacPorts and then reinstall the ports you want; the
 [wiki:Migration migration instructions] provide some guidance on how to do
 that.
