The only file I can see that looks relevant is
    /Library/Receipts/boms/org.haskell.glasgowHaskellCompiler.ghc.pkg.bom

Wouldn't removing it make uninstall impossible?

In fact, if you did manage to get 2 versions installed, how would
    /Library/Frameworks/GHC.framework/Tools/Uninstaller
know which version to uninstall? Wouldn't it only know how to uninstall
the version it came with? I'd suggest that the overlapping file
"Uninstaller" could be why the older version gets removed, but that
wouldn't explain why Manuel can install both at once.


Thanks
