The syntax of package descriptions has changed. Documentation for the new format is here: http://www.haskell.org/ghc/docs/latest/html/users_guide/packages.html#in stalled-pkg-info
Packages always were difficult. And in 6.4 they are changed again ...
I'd urge you to look at using Cabal for your library, I think it'll simplify things for you a lot. In particular, you won't have to deal with ghc-pkg and you won't have to write any Makefiles. Cabal is specifically designed to make life easier for people like you! I know changes are painful, but in this case they weren't gratuitous. All the changes were to support Cabal, and we believe this is the right direction to go. If it all pans out, we won't need to make any big changes again in the future.
Question 2: recompilation -------------------------
Why does it recompile both modules when after the first make dm we remove the .a library and repeat make dm ? This recompilation bites when there are many modules.
Unfortunately your use of -ddump-hi-diffs has forced recompilation. This is a bug: we changed it so that all -ddump-* flags forced recompilation because in most cases some intermediate output has been requested. However, -ddump-hi-diffs should be an exception. Thanks for the report - just turn off -ddump-hi-diffs. Cheers, Simon
