Are you sure it does deinstall the 6.8 compiler?

After installing 6.10, there should be a 608/ and a 610/ directory. This certainly happens on my Mac and I am not aware of an option to change that behaviour.

I expect if you used the OSX installer then /Library/Receipts is screwing you (it wipes the old files listed in the .bom file). Try finding and removing the receipt directory and bom file before installing.

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 Ian
