Are the plugins directories necessary for client code?

[redfloyd@gmail.com]

I'm building on a platform that has a half-assed posix environment
(amazingly enough, it's *NOT* Windows), and the makefiles for the
plugins (specificly db2) are blowing up.

The company I'm contracting to has an existing product that a client
wants kerberized.  As such, it's really only the client code (libkrb5,
clients/*).  Do I need to build the plugins for everything to work
properly?

Thanks.
