This is probably a bug with the dependent ports from a MacPorts angle, since we want the compiler the Portfile/base specifies used, not what 'apr-1-config --cc' returns.  Force reinstalling the ports caching paths to the toolchain allowed the remaining ports to be built.  Some variant of the migration upgrade steps is probably required to make sure nothing has /Developer paths stored away…

This isn't a problem with libtool at least since the build systems still
obey CC in the configure environment. You do get problems if they then
neglect to use the appropriate --tag argument when invoking libtool, but
that can and should be patched.
