[Haskell-beginners] Error in Installing Data.deriveTH

[mukesh tiwari]

Hello all
I am trying to install Data.deriveTH . When i tried cabal install derive , i
got this error.

ntro at ntro-HP-dx2480-MT-NA121PA:~/Mukesh/assignment_haskell/work$ cabal
install deriveResolving dependencies...<command line>: cannot satisfy
-package Cabal-1.10.2.0:
    Cabal-1.10.2.0-072fce39d68f011c6a364057a3d15270 is unusable due to
missing or recursive dependencies:
      containers-0.3.0.0-ee442470d8dcc9e45f31677c400c5379
    (use -v for more information)cabal: Error: some packages failed to
install:derive-2.5.4 depends on haskell-src-exts-1.11.1 which failed
to install.haskell-src-exts-1.11.1 failed during the configure step.
The exception was:ExitFailure 1

installed. All the requested packages are already installed.If you
want to reinstall anyway then use the --reinstall flag.


I tried to resolve this issue on #haskell and i got suggestion    that
it was due to conflict in global and local namespace [ see   here for
more detail http://hpaste.org/51376 ]. One idea is i     should wipe
~/.ghc and install all the libraries individually.    Could    some
one please suggest if there is another idea to      resolve this
issue. Currently i have ghc-6.12.3  and  installing ghc-7.0 will
resolve the issue ?


Thank you
