According to Debian Testing they are using a snapshot of GnuBG source from
November 2006. The multithreaded support was released around the end of
January 2007.

The one thing I can recommend is pulling the latest source code out of CVS
(Or downloading a recent snapshot of the source) and building the
Multithreaded version on Debian.

I don't know if it will compile without errors on Debian but you can try.
Snapshot can be found here:


If you want to us CVS information can be found here:
