 there is only one time package installed, so i'm surprised to see any
 package prefixes at all here
 {{{
 $ ./ghc-6.9.20080514/bin/ghc-pkg.exe find-module Data.Time.\*
 c:/fptools/ghc/ghc-6.9.20080514\package.conf:
     time-1.1.2.0
 }}}
 but by what system do some things get prefixes and others don't? are there
 any invisible modules that need the distinction, or is this an output bug?
