[Haskell-cafe] Newbie; Can't Install Hat From Source

[Aditya Siram]

Hi all,
I have been trying to install Hat for the last couple of days but GHC does 
not recognize it as a package. I compiled 2.05 from source, but at the 'make 
install' step I see this error message:

**Begin Output**
./configure --install
Configuring for hat... [ 2.05 ]
Starting with earlier config in targets/ix86-Linux/config.cache
[ config: ix86-Linux/ by deech at ubuntu on 15 Nov 2006 ]
  (but cmdline options have precedence)
--------
Looking for already-installed Haskell compilers:
  Looking for ghc...   found 6.6
  Looking for nhc98... (not found)
  Looking for hmake... found 3.13
You said you want to use ghc to build hat.
Done.
--------
                   Configuration report for hat.

You are going to build hat with:            ghc
Executables need .exe suffix?               no  (detected)
Testing for the glib library:               no  (using slower replacement)

Installation directories are now created/checked.
Install directory root is:
    /usr/local

    /usr/local/include/hat-2.05 (exists)
        Array.hx

**End Of Output**

The output of 'ghc-pkg list' is:

/usr/local/lib/ghc-6.6/package.conf:
    Cabal-1.1.6, HUnit-1.1, QuickCheck-1.0, base-2.0, cgi-2006.9.6,
    fgl-5.2, (ghc-6.6), haskell-src-1.0, haskell98-1.0, html-1.0,
    mtl-1.0, network-2.0, parsec-2.0, readline-1.0, regex-base-0.71,

/home/deech/.ghc/i386-linux-6.6/package.conf:
    (hat-2.4)   <----ERROR!!!

For some reason it thinks that hat-2.4 is installed.

I tried to run a test program saved in HatTest.hs:

import Prelude

main = do { print "Hello"; }

When I compile it with 'hmake -hat HatTest' I get the following error:
hat-trans   HatTest.hs
Wrote Hat/HatTest.hs
ghc-6.6      -c -package hat -o Hat/HatTest.o Hat/HatTest.hs

Hat/HatTest.hs:3:0:
    Bad interface file: 
/usr/local/imports/hat-2.05/ghc-606/Hat/PreludeBasic.hi
        Something is amiss; requested module  hat-2.4:Hat.PreludeBasic 
differs from name found in the interface file hat:Hat.PreludeBasic

I'm not really sure how to proceed. Any help is appreciated.

BTW I get the ghc-package: cannot find package hat when I 'apt-get install' 
it too.

Thanks..
Deech
