# Brief explanation of the bootstrap logic:
#
# ghc requires ghc-bin to bootstrap.
# Therefore,
# (1) both ghc-bin and ghc provide virtual/ghc
# (2) virtual/ghc *must* default to ghc-bin
# (3) ghc depends on virtual/ghc
#
# This solution has the advantage that the binary distribution
# can be removed once an forall after the first succesful install
# of 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.
