[Hat] Using Hat with HUnit

[Katerina Barone-Adesi]

I'm trying to run hat on some unit tests.  They use HUnit-1.0, which I
have under the tests directory, in tests/HUnit-1.0/; I've been
interpreting the tests using runhaskell.
When I run hmake -package parsec -i.. -iHUnit-1.0 RunTests;
./RunTests, everything works exactly as it does when I'm interpreting.
 When I add a -hat to the options, I get the following error:

hat-trans   -i.. -iHUnit-1.0 HUnit-1.0/HUnitLang.lhs
Wrote Hat/HUnit-1.0/HUnitLang.hs
/usr/bin/ghc   -package parsec   -i.. -iHUnit-1.0  -c -package hat -o
HUnit-1.0/Hat/HUnitLang.o HUnit-1.0/Hat/HUnitLang.hs
ghc-6.4.2: error: directory portion of "HUnit-1.0/Hat/HUnitLang.o"
does not exist (used with "-o" option.)

If I manually create HUnit-1.0/Hat:
hat-trans   -i.. -iHUnit-1.0 HUnit-1.0/HUnitLang.lhs
Wrote Hat/HUnit-1.0/HUnitLang.hs
/usr/bin/ghc   -package parsec   -i.. -iHUnit-1.0  -c -package hat -o
HUnit-1.0/Hat/HUnitLang.o HUnit-1.0/Hat/HUnitLang.hs
ghc-6.4.2: file `HUnit-1.0/Hat/HUnitLang.hs' does not exist

If I switch into the HUnit-1.0 directory and run "hmake -hat HUnitLang.lhs":

hmake -hat HUnitLang.lhs
hat-trans   HUnitLang.lhs
Wrote Hat/HUnitLang.hs
/usr/bin/ghc      -c -package hat -o Hat/HUnitLang.o Hat/HUnitLang.hs

                                                                       (+++)

I'd like to be able to trace my code; I'm indifferent to whether or
not I trace the code within HUnit.  Any suggestions on how I can do
this?
