Comment (by George):

 This doesn't seem to be a problem on the 7.10.2 alpha Haskell Platform:

  ghc --version
 The Glorious Glasgow Haskell Compilation System, version 7.10.1.20150601

  cabal install  --ghc-options="-O2" accelerate --reinstall
 cabal install  --ghc-options="-O2" accelerate --reinstall
 Resolving dependencies...
 In order, the following will be installed:
 accelerate-0.15.1.0 (reinstall)
 Warning: Note that reinstalls are always dangerous. Continuing anyway...
 Configuring accelerate-0.15.1.0...
 Building accelerate-0.15.1.0...
 Installed accelerate-0.15.1.0
 Updating documentation index
 /Users/gcolpitts/Library/Haskell/share/doc/x86_64-osx-
 ghc-7.10.1.20150601/index.html

 fwiw the following didn't give an error but not sure if it did the "right"
 thing, in any case the above should be definitive

  cabal install -j3 -O2 accelerate
 cabal install -j3 -O2 accelerate
