Certainly the one or two "pure Haskell" packages out there (e.g.,
PureMD5) seem to build without issue. The trouble is that almost all
useful Haskell packages are bindings to C libraries, and that varies by

As I say, last time I tried this, I'd just failed to build half a dozen
other interesting packages, so by the time I'd got to trying to get
database access working, I was frustrated to the point of giving up.

confused. (It built OK on OpenSuSE, but appears not to like Ubuntu very
