5394	GHC hangs on compile of anything	beezir		"I'm probably doing something wrong, but I have a fresh install of Haskell Platform 2011.2.0.1 which includes GHC version 7.0.3.  Under Windows 7 x64, I can not get it to compile even the simplest program without hanging.  The source I am compiling is as follows:
{{{
main = putStrLn ""Hello, world!""
}}}

ghc --make helloWorld.hs hangs here:
{{{
[1 of 1] Compiling Main             ( helloWorld.hs, helloWorld.o )
}}}

It never exits even if left for hours.  Attempting compile with -v gives the following and then hangs:
