Comment (by ryandesign):

 `-macosx_version_min not specificed` is also interesting (not only for the
 typo of "specified") but because MacPorts already sets
 `MACOSX_DEPLOYMENT_TARGET='10.5'` in all phases, which is supposed to be
 equivalent to the compiler flag `-mmacosx-version-min` and the linker flag
 `-macosx_version_min`.

 From closer inspection of the log, I see that `MACOSX_DEPLOYMENT_TARGET`
 is actually not getting set here. And this is because the failure is
 occurring in code run by a pre-configure block. The block of code goes to
 some lengths to attempt to replicate what MacPorts does in the standard
 phases, including setting several of the usual environment variables, but
 it has neglected to set `MACOSX_DEPLOYMENT_TARGET`.
