As I think you can see, hat-trans and hmake are disagreeing about where
the Hat-translated versions of the source-code should live.  hat-trans
thinks
        Hat/HUnit-1.0/HUnitLang.hs
whilst hmake thinks
        HUnit-1.0/Hat/HUnitLang.hs
(the inital portion is swapped around).

The main reason for this is a differing interpretation of the -i flag
(giving a directory where extra source files live).

One workaround is to move all the HUnit code to the current directory,
rather than a separate directory.

Another workaround is to change the name of the HUnit directory, so it
no longer begins with upper-case, e.g. hunit-1.0.  I know this is
somewhat fragile, but the only way some tools know how to distinguish
between the filename of a simple module, and the pathname of a
hierarchical module, is on the case of the first letter of the directory
part.

I hope one of these suggestions is useful.  If not, please post again!
