Can't install Criterion package on ghc ..

[Mozhgan kabiri]

Hi,

I am trying to install Criterion package, but I keep getting an error and I
can't figure it out why it is like this !!

mozhgan at Mozhgan-KCh:~$ cabal install Criterion

Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

cabal: Error: some packages failed to install:
criterion-0.5.0.0 depends on vector-algorithms-0.3 which failed to install.
statistics-0.5.1.0 depends on vector-algorithms-0.3 which failed to install.
vector-algorithms-0.3 failed during the building phase. The exception was:
exit: ExitFailure 1

I tried to install Statistics and vector-algorithms package separately
before installing the Criterion package itself .. but it wasn't successful.

Thanks,

Mozhgan
