[jhc] Building cabal packages

Hey everyone, What's the way to build a cabalized package with jhc? I tried the following:

hc --build-hl Yampa.cabal yampa-0.9.2.3.hl jhc --build-hl Yampa.cabal yampa-0.9.2.3.hl jhc 0.7.3 (-n 0.7.2-40 ) Creating library from description file: "Yampa.cabal" Reading: "Yampa.cabal" Finding Dependencies... Using Ho Cache: '/Users/chris/.jhc/cache' Typechecking... Compiling... Writing Library: Yampa-0.9.2.3.hl

But I don't think jhc actually compiled something, or it was *really* fast. I tried copying that .hl file to my JHC_LIBRARY_PATH, but when I invoke JHC with "-pyampa" it still won't find it. I'm a bit lost... -chris
