One other thing.  There are tons of config scripts like gtk-config.
These all include -Wl,-R for setting the RPATH.  Darwin neither has
nor needs RPATH; it's sort of implied just by linking in a library.
Personally, i think Apple needs to make their linker take a no-op -R
flag, but until they do, pkgsrc will have to work around it somehow if
it wants to be of use on Darwin.

Told you i'd forgotten something :).
