If the latter, then the relevant ghc-bin for the # arch in question will be used in the working directory to compile # ghc from source. # # This solution has the advantage of allowing us to retain the one # ebuild for both packages, and thus phase out virtual/ghc. # Note to users of hardened gcc-3.x: # # If you emerge ghc with hardened gcc it should work fine (because we # turn off the hardened features that would otherwise break ghc). # However, emerging ghc while using a vanilla gcc and then switching to # hardened gcc (using gcc-config) will leave you with a broken ghc. To # fix it you would need to either switch back to vanilla gcc or re-emerge # ghc (or ghc-bin). Note that also if you are using hardened gcc-3.x and # you switch to gcc-4.x that this will also break ghc and you'll need to # re-emerge ghc (or ghc-bin). People using vanilla gcc can switch between # gcc-3.x and 4.x with no problems.
