What other changes?  I don't recall having to make any other changes
when I compiled gmime.

That should not have been needed.  Hmm, perhaps pcre hasn't been
properly compiled.  For one it requires a patched version of libtool to

Since both pan & gmime depend on pcre this could be the problem.  Oh, i
also configure with --enable-utf8 --enable-unicode-properties.  Hope
