John,

Nice to know.  Thanks.  But in this case I may have mis-diagnosed the
problem.  There are paths embedded in the dylibs provided in the package
and the "not prebound" error led me to believe that was the porblem.  But
the error occurs during the build before the app is created and I suppose
the cause problem may be different than I thought.  If the build would
complete I think I could do as you suggested.  But this is such an
unfriendly app that my interest is mostly academic at this point anyway.

/usr/bin/ld: warning prebinding disabled because dependent library:
/sw/lib/libglib-2.0.0.dylib is not prebound
/usr/bin/ld: Undefined symbols:
_g_return_if_fail_warning
_g_assert_warning
collect2: ld returned 1 exit status
** BUILD FAILED **
