Compiling libs only

Hi,

question that i couldnt get answered in Questions, so at the risk of 
being shot sending it here.

Is it possible to compile only lib(pq) and not the rest of the DBMS.
I'm facing the problem where i have to install client software on
multiple platforms, and wanting to make C stubs for the applications.
Building the entire DBMS on every platform is no option (space limits).
I have already tried a config, then compile in the interfaces/lib
dir, but that does not seem to work. Unfortunately i am not yet fully
up to date with knowledge of the sources, so making a 'make lib' isnt
within my powers......

Any suggestions?
