[Haskell-cafe] Cabal in ghc 6.4.2

[allan]

Hello all,

(before I start I should say I'm relatively new (a few months) to 
haskell, so I'm not exactly savvy with the use of the compilers)

I have a problem using the cabal with version 6.4.2 of ghc, the same 
thing occurs with two projects which I wish to compile, I'll use the 
simplest one since the problem seems to be the same in both cases.
The program is a very simple printer thing for haskell the source of 
which you can download at:
http://homepages.inf.ed.ac.uk/s9810217/software/haskell_print/haskellprint.tar.gz 
<http://homepages.inf.ed.ac.uk/s9810217/software/haskell_print/haskell_print.tar.gz>
(but you probably won't need to, in order to diagnose this problem)

I wish to compile this with the sequence of commands:
./Setup.hs configure --user --prefix=/home/allan/install
./Setup.hs build

this works perfectly on version 6.4 of ghc,
however with version 6.4.2 I get the following error:

haskellprint$ ./Setup.hs  build
Preprocessing executables for haskellprint-0.1...
Building haskellprint-0.1...
Chasing modules from: Main.hs
Could not find module `Text.ParserCombinators.Parsec':
  use -v to see a list of the files searched for
  (imported from ./Parser.hs)
haskellprint$

Now if I run
haskellprint$ ./Setup.hs build --verbose


then I can see the command line used to compile the program which is:
/home/allan/install/bin/ghc -Idist/build -o 
dist/build/haskell_print/haskell_print --make -Wall -hide-all-packages 
-i -idist/build/autogen -i. -odir 
dist/build/haskell_print/haskell_print-tmp -hidir 
dist/build/haskell_print/haskell_print-tmp -package base-1.0 Main.hs

If I copy and paste this into the command line and remove the argument [ 
-hide-all-packages ]
then the program compiles fine.
So basically my question is: what am I doing wrong? I assume my problem 
is in the .cabal file, so I include the contents here:

thanks in advance for any help.
