I need to build a private keyserver for interanl use.

I have tried to get SKS to build, but I have never been able to get it to work.  (The project seems to be almost abandoned.)  I am using Fedora 9 on an x86_64 box with 4 gigs of ram and Numerix blows up on compile with "out of memory" errors.

I have not seen anything else that handles subkeys.

Any recommendations?
