Trouble installing System.FilePath.Find

Question

I want to install System.FilePath.Find module. I tried using

cabal install FileManip

but it failed:

Resolving dependencies...
Configuring FileManip-0.3.3.1...
Preprocessing library FileManip-0.3.3.1...

cabal: Error: some packages failed to install:
FileManip-0.3.3.1 failed during the building phase. The exception was:
ExitFailure 1

What am I doing wrong?

$  ghc --version
The Glorious Glasgow Haskell Compilation System, version 6.12.1
$  cabal --version
cabal-install version 0.8.0
using version 1.8.0.2 of the Cabal library 

Answer 1

The FileManip package is marked as obsolete on Hackage and the last version is from 2010.

Use filemanip (lower case) instead. It should be more up to date.

You might also want to upgrade your GHC. Version 6.12.1 is from December 2009.
