Problem installing GLFW-0.4.2 on WinXP x86 32-bit using cabal

[Michael Chin]

Hi,
 I noticed another posted here about issues installing GLFW and was
wondering if someone could help me resolve why I am unable to build GLFW.
I'm required to install GLFW for a class assignment. Any suggestions or
help would be greatly appreciated. Thanks.

Here is the console output:
$ cabal install GLFW
Resolving dependencies...
Configuring GLFW-0.4.2...
Preprocessing library GLFW-0.4.2...
Building GLFW-0.4.2...
[1 of 1] Compiling Graphics.UI.GLFW ( Graphics\UI\GLFW.hs,
dist\build\Graphics\UI\GLFW.o )

Graphics\UI\GLFW.hs:1002:24:
    Ambiguous occurrence `unsafePerformIO'
    It could refer to either `Foreign.unsafePerformIO',
                             imported from Foreign at
Graphics\UI\GLFW.hs:85:1-14
                          or `System.IO.Unsafe.unsafePerformIO',
                             imported from System.IO.Unsafe at
Graphics\UI\GLFW.hs:89:1-23

....

(More of the same errors)

....

cabal.exe: Error: some packages failed to install:
GLFW-0.4.2 failed during the building phase. The exception was:
ExitFailure 1

Is there something wrong with my environment?

Environment:
WinXP x86
Cygwin

$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.2.2

$ cabal --version
cabal-install version 0.10.2
using version 1.10.2.0 of the Cabal library

Thanks in advance,
 Michael
