I can't really tell what might have gone wrong with your installation on Fedora without additional details, such as: what did you actually do for the installation. But it definitely should be possible to install GHC on Fedora.

I switched to installing language tools somewhere in my home directory 
long ago, because
- more frequent breakage than for other types of packages
- I want a newer version anyway
- common permission issues when installing plugins/libraries

My guess about the reasons:
- package tools don't have a concept of user-installable extension
   so many language tools are broken by design (I'm looking at you,
- the packaged version tends to be older than what you wanted; the
   faster the language evolves, the more this is a problem
- language tools tend to be complicated and fragile, so they have a
   higher chance of breaking anyway
- if there's an issue, the easiest fix for most users is to just install
   the language tools in the home directory, instead of fixing the
   package (which often is too slow to solve the immediate problem -
   this might be different for rolling-release distros, I never tried
   one of these)
