------------------------+---------------------------------------------------
 According to section 5.8.4.1 of the ''Users' Guide'', appending a colon to
 GHC_PACKAGE_PATH should include the system libraries, and this can be
 verified with ghc-pkg. While the colon does appear to work for ghci (as
 verified with -v), it does not appear to work for ghc-pkg.

 {{{
 $ echo '[]' > temp.conf
 $ export GHC_PACKAGE_PATH=`pwd`/temp.conf:
 ghc-pkg list
 /home/cjs/temp.conf:
 $
 }}}
