Comment (by ballapete):

 Actually only one difference is left:

 {{{
 diff ~/local/devel/elftoolchain/Portfile
 /opt/local/var/macports/sources/nue.de.rsync.macports.org/macports/release/tarballs/ports/devel/elftoolchain/Portfile
 66,70d65
 < platform darwin 10 {
 <       depends_lib-append          port:snowleopardfixes
 <       configure.ldflags-append   -lsnowleopardfixes
 < }
 <
 }}}

 Updated `Portfile`s either have this "patch" included or a

 {{{
 PortGroup           snowleopard_fixes 1.0
 }}}

 statement. So most of my `local` versions have become obsolete.

 Anyway, I am rebuilding/reinstalling `clang-3.9`, `llvm-3.9`, `cctools`,
 `ld64-127`.
