I think that:

./configure --with-ghc-flags=3D-package-conf=3D/Users/rherk/soft/package.=
conf

should work, but I haven't tested it.

I think that the problem is that when the configure script checks for=20
the presence of some module, it uses ghc, not ghc-pkg, since ghc must be=20
able to find the module later during the compilation. I guess you could=20
make another script which calls ghc and uses your local package conf.=20
You could then use --with-ghc to use it for compilation. Using=20
--with-ghc-flags as above should also work.
