I rebuilt job 996 (gc for FC4/x86_64) in the build system and took a
look at the installed buildroots.  There does exist:


So I'm not really sure where libtool (evil, evil thing) thinks it's not
getting the libs from since they clearly exist...  I tend to blame
libtool for anything that remotely resembles stupidity of linkage, your
results may vary.  That said, libtool hasn't been known to play the
nicest with multilib in the past.
