Comment (by Ionic):

 Good, that seems to work:

 {{{
 %  nm -arch x86_64 $(port work legacy-
 support)/destroot/opt/local/lib/libMacportsLegacySupport.dylib | grep -i
 fdopendir
 0000000000002aa5 T _fdopendir
 0000000000002bb1 T _fdopendir$INODE64
 %  nm -arch i386 $(port work legacy-
 support)/destroot/opt/local/lib/libMacportsLegacySupport.dylib | grep -i
 fdopendir
 00002a55 T _fdopendir
 00002c6f T _fdopendir$INODE64$UNIX2003
 00002b62 T _fdopendir$UNIX2003
 }}}

 This stuff still seems very fragile...

 Ken, you do have access to ppc machines, right?

 I'd like to see the output of

 {{{
 % nm -arch ppc /usr/lib/system/libsystem_c.dylib | grep opendir
 % nm -arch ppc64 /usr/lib/system/libsystem_c.dylib | grep opendir
 }}}

 on a 10.5, 10.6, and, if possible, also a 10.4 machine.

 I need to know how to tweak that stuff for `ppc` and `ppc64`.

 10.4 is interesting because the first UNIX-certified version was 10.5 as
 far as I remember, so I suspect that 10.4 won't have $UNIX2003-postfixed
 symbols. In that case, I'd like to make the `fdopendir` implementation
 10.5+ only.
