We should be able to work around this. Both buildlink2 and buildlink3
(hereafter "bl2" and "bl3") can strip -Wl,-R* or -R* from files before
they're installed, and we just need to identify which files those are.
By default, we do this on files matching *-config, *Conf.sh, and *.pc.

I believe I've fixed this in bl3. When we eventually switch bl2
packages to use bl3, this problem should just go away, along with all
other cases where a package installs a .la file for a library that is
also in one of the system library paths.

I just read your bug report there (for anyone else who's curious, it's
bug #851 on opendarwin.org). I'll try to implement the ln/cp idea in
a way that lets us isolate its use.
