Uh, x11-links should have shlib handling turned off. I'll look into that:

This looks a little strange. It shouldn't be doing the shlib chmods in that
case. I'll fix.

I want to make sure all packages are watched for improper permissions [on
all platforms using ELF/a.out-style shlibs] so that the package maintainers
will fix these things. Even if some platforms have loose permissions, it is
a bug, and should not be foisted upon just one person or a small group of
persons to clean up everyone else's mess.
