Problems with hat

[max.e.brown at gmail.com]

I just installed hat and tried using it, but something appears to have
gone wrong with the install:

-8<--------------------------------
$ hmake -hat fib.hs
hat-trans   fib.hs
Wrote Hat/fib.hs
ghc      -c -package hat -o Hat/fib.o Hat/fib.hs

Hat/fib.hs:3:0:
    Failed to load interface for `Hat.PreludeBasic':
      Use -v to see a list of the files searched for.
-----------------------------------

Ooops. I check where it looks for Hat.PreludeBasic:

-8<--------------------------------
$ hmake -hat -v fib.hs
hat-trans   fib.hs
Wrote Hat/fib.hs
ghc   -v    -c -package hat -o Hat/fib.o Hat/fib.hs

Hm. I check and find that my hat has some file like that in
/opt/local/imports/hat-2.05/ghc-606/Hat, and try

-8<--------------------------------
$ hmake -hat -I/opt/local/imports/hat-2.05/ghc-606 fib.hs
hat-trans   -I/opt/local/imports/hat-2.05/ghc-606 fib.hs

Hat/fib.hs:3:0:
    Bad interface file: /opt/local/imports/hat-2.05/ghc-606/Hat/PreludeBasic.hi
        Something is amiss; requested module  main:Hat.PreludeBasic differs from name found in the interface file hat-2.5:Hat.PreludeBasic
-----------------------------------

hat-2.5 versus hat-2.05? I am not sure what's going wrong here.

Any hints appreciated.

Thanks,

Max
