Hi Ivan,
I tried doing 
> cabal install "parsec >= 3" --reinstall --enable-library-profiling
This complained about bytestring ... so I did this -
> cabal install "bytestring" --reinstall --enable-library-profiling
And this complained about base - 
Data/ByteString.hs:278:7:
    Could not find module `GHC.ST':
      Perhaps you haven't installed the profiling libraries for package `base'?
      Use -v to see a list of the files searched for.
cabal: Error: some packages failed to install:
bytestring-0.9.1.5 failed during the building phase. The exception was:
exit: ExitFailure 1
[kashyap@trinity318 ~]$ cabal install "base" --reinstall --enable-library-profiling 
Resolving dependencies...
cabal: internal error: impossible


Am I missing something?

How did you install parsec?  You need to rebuild it with profiling
library support.  If you used cabal-install, you have two options:

1) set library-profiling to True in ~/.cabal/config and then
   cabal install parsec --reinstall
2) cabal install parsec --reinstall --enable-library-profiling

This has nothing to do with GHC.
