No, both environments do not have cpphs installed.

Yes, but this seems like exactily the kind of thing we'd like to avoid.

The major difference between the two machines seems to be the version of
cabal.  On my mac (where compilation works), cabal version 1.0 is
installed, whereas on my gentoo machine cabal 1.1.3 is installed (both
with GHC 6.4.1).

Neither command line has a '-I' option.

Any ideas?
