Well, I tried that and I ended up with a Python without readline
support and Singular failed to build at all without it. These were
strange failures to say the least. clisp also has trouble IIRC.

I don' think it will work - it didn't on my OpenSUSE 11.1 install :).
Other than that if we get it to work I would be fine with that
solution since we so rarely update readline that it won't matter if we
link static or dynamic libs in this case.
