That does the job, Thanks !!
Just to understand what is happening under the hood I tried to resolve this to the exact steps. The problem I faced seems to be equivalent of missing a -L and -l in gcc. Looking at the man for ghc I did find it had the -l and -L flags. Now I had to find the path and the name of the library. Did a find over the location I have installed ghc I was able to short list the likely candidates.
,----
| find /opt/ghc-6.10.1/ -type f |grep \\.a$ | ....
/opt/ghc-6.10.1/lib/ghc-6.10.1/bytestring-0.9.1.4/libHSbytestring-0.9.1.4.a
/opt/ghc-6.10.1/lib/ghc-6.10.1/bytestring-0.9.1.4/libHSbytestring-0.9.1.4_p .a
| ....

and as expected adding the -l and -L in the ghc command line does the trick.
/opt/ghc-6.10.1/bin/ghc -L/opt/ghc-6.10.1/lib/ghc-6.10.1/bytestring-0.9.1.4/ -lHSbytestring-0.9.1.4 cp.hs

Or, simpler: ghc -package bytestring -o anfile anand.hs but I strongly recommend using --make for every compilation unless you know that you really do *not* want it.
