I can't really recompile mtl with profiling considering that just about every single package on my system seems to depend on it and they would (probably?) all break.

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.

I compiled it all myself and am not using my distro's (Gentoo) package manager for any Haskell packages. Will I have to recompile GHC (and everything that comes with it)? If yes, what flags should I pass to get profiling for the libs? The version in question is 7.6.3. -- Mateusz K.
