Installing haskell platform fails

I am trying to install haskell-platform-2011.2.0.1 onto my suse 11.4. I have got the all the dependencies required for the ./configure with works ok. But on getting to "make", it builds with this error

scripts/build.sh

    Could not find module `Sys开发者_开发技巧tem.IO':
      Perhaps you haven't installed the profiling libraries for package `base'?
      Use -v to see a list of the files searched for.

Error:
Building the transformers-0.2.2.0 package failed
make: *** [build.stamp] Error 2

I have googled around but not one seems to have the right solution. How do install the missing 'System.IO' module?

For the record, the problem was likely that the ghc package used for the build did not have profiling libraries included.
