Does anyone have any suggestions on how to approach the problem? Am I
doing it all wrong?

How did you install ghc and the Haskell Platform? Vendor packages on Linux may split out the profiling libraries into separate packages (e.g. on Fedora 19 ghc-mtl-devel includes the profiling libraries, but on Debian wheezy they're separated into libghc-ghc-mtl-prof instead of being in libghc-ghc-mtl-dev). Installing such packages will not break anything using the existing -dev packages' libraries.
