Most likely, you did not have libdes installed.  Some of the patches
included in the jumbo patch require libdes.

FWIW, I think someone (Erik?) should update the patch to compile with
OpenSSL instead of with the standalone libdes.  This should be trivial
to do.  It is far more common to readily have OpenSSL installed.

If you submit it (or if someone else does), I'd be happy to include such
a Windows binary in contrib.
