I don't think so, at least not yet. If Sage builds fine and passes all
doctests except for this one detail, then perhaps we should bring it
up again at that point, but it really sounds like a bug in the
OpenSolaris linker (not being able to build gnutls) and adding a
prerequisite seems like a heavy-handed fix.
