Comment (by kencu):

 You can't reliably combine c++ ports built with libc++ and gcc's libstdc++
 without eventually running into some kind of disaster, especially when you
 have something that is as integrated into other ports as much as `mesa`
 is. So you should build it with clang, and disable TLS.

 To build mesa on 10.6 with libc++, the following additions to the portfile
 are necessary, but not sufficient:
 {{{
 configure.args-append --disable-llvm-shared-libs
 configure.args-append --disable-glx-tls
 configure.cppflags-append -DO_CLOEXEC=0
 }}}

 after doing the steps mentioned, it will still fail to build due to
 [ticket:54638], which so far has no solution.
