[Haskell-beginners] Cabal dependencies problem

[Jun HU]

Hello everyone,

I've some problems with cabal dependency mechanism. For example,
when i try to install package "funsat",

:> cabal install funsat

 it shows

====================== MSG =================== BGN
Registering parsec-3.1.1...
Installing library in /home/jhu/.cabal/lib/parsec-3.1.1/ghc-6.12.1
Registering parsec-3.1.1...
cabal: Error: some packages failed to install:
array-0.2.0.0 failed during the building phase. The exception was:
ExitFailure 1
bimap-0.2.4 depends on array-0.2.0.0 which failed to install.
containers-0.2.0.1 depends on array-0.2.0.0 which failed to install.
fgl-5.4.2.2 depends on array-0.2.0.0 which failed to install.
funsat-0.6.1 depends on array-0.2.0.0 which failed to install.
parse-dimacs-1.2 depends on array-0.2.0.0 which failed to install.
====================== MSG =================== END

while the current array package is on version array-0.3.0.2.  The package
has back compatibility problem.  Any advice is appreciated...  thank you in
advance.

Sincerely,

Jun
