Ok, I read the the statements on their copyright page again, and it
seems that most parts are covered by the LGPL or the GPL.  There is
one problem, however:

3. Some parts of the source (the regexp library) are covered by a
   Berkeley-style copyright.

This is not very clear.  I *assume* this refers to the original BSD
license without looking at the source code.

http://www.gnu.org/licenses/license-list.html#OriginalBSD

There, it says:

    This is a simple, permissive non-copyleft free software license
    with a serious flaw: the ``obnoxious BSD advertising clause''. The
    flaw is not fatal; that is, it does not render the software
    non-free.

I therefore suggest we apply the first patch.  I have changed another
doc string in the mean time as well, so the resulting patch includes
another hunk.

Alex.
