     But Duncan, let's suppose I build "unix" putting in a "local" directory
with a different version number than the released version of "unix".

     1) How do I get the "local" package.conf built and populated?

     2) How do I get a test case to link against this experimental local
version of "unix"? Is there a "--prefix" or something like that I pass on
runhaskell Setup.hs build?

Regards, Vasili
