Ok, that means less work for the extension facility (it was not
targetted for it's first incarnation anyway) stuff.

FWIW, I had in mind to use the dependancy information in the extension
meta-data to issue more than one "dlopen()" when a plugin function is
called. I'm being told that in my case linking uuid-ossp.so against
uuid.so should do the trick, though.

I'll drop the idea off the scope of the extension facility.
