 I'm running a Gentoo system and use the haskell overlay. The Gentoo-
 Haskell folks strongly advise using their provided packages instead of
 cabal-install.

 When I try to emerge (=install) [dev-
 haskell/happy-1.18.10](http://www.haskell.org/happy/) the build process
 aborts with the message


 {{{
 >>> Compiling source in /var/tmp/portage/dev-
 haskell/happy-1.18.10/work/happy-1.18.10 ...
 ./setup build
 setup: internal error: evacuate: strange closure type 2122076
     (GHC version 7.6.1 for x86_64_unknown_linux)
     Please report this as a GHC bug:
