odd GHC 6.8.2 compile failure

[Isaac Dupree]

linking the compiled stage2 failed when bootstrapping from 6.6.1, with 
--prefix=$HOME .

It's odd because I previously had a 6.8.2 (official x86 Linux bin-dist) 
installed as root (it's gone now), and I still have a bunch of 
cabal/hackage packages installed in $HOME that were compiled by that 
6.8.2 (in addition to a few things installed by `cabal install` in 
~/.cabal/).  Do you think that could be confusing the build process, and 
if it is, is that a bug - and a bug in what?
