Comment (by jeremyhu@…):

 This comment in the Portfile suggests that the problem is with the build
 system itself:
 {{{
 # Clear all options that affect CFLAGS and CXXFLAGS, since the configure
 # script tries to build the fastest library for the build machine if
 # CFLAGS and CXXFLAGS are undefined.
 #
 # Append the -stdlib flags to CXX, since we still want to select the C++
 STL.
 #
 # On PowerPC machines, CFLAGS must be empty to get -force_cpusubtype_ALL.
 }}}

 We should fix that bug properly and upstream the changes, so other
 packagers benefit as well.
