GHC.Paths makes incorrect assumption as to where to find ghc #4

I hen trying to set up taffybar (xmonad toolbar) which uses Dyre which in turn uses ghc-paths and ran into a problem.

I have a couple of different versions of GHC installed (7.4.2, 7.6.3 and 7.7) all installed under $HOME/GHC/$version and I switch between them by setting my $PATH variable. When Dyre tires to re-compile the taffybar config file, ghc-paths says that the ghc binary is at "/usr/lib/ghc/bin/ghc-7.6.3" when it is actually at $HOME/GHC/7.6.3/bin/ghc-7.6.3.

use ghc from PATH instead of hardcoded one #23
