 > My version of the Portfile seems to miscompile ghc. I don't yet know
 why, I'll try to have a look tomorrow.
 Damn, what variant? My extensive testing (that is compiling a hello world

 the gcc47 variant works.

 Did you run the test suite? Perhaps we could automate the checking of
 various
 gcc variants. The current included list is just taken from the Portfile
 guide.
