 I have this module:

 {{{
 {-# LANGUAGE TemplateHaskell #-}

 module A where

 foo = [| 3 |]
 }}}

 Now, I do this in ghci:

 {{{
 > :seti -XTemplateHaskell
 > :load A.hs
 [1 of 1] Compiling A                ( A.hs, interpreted )
 Ok, modules loaded: A.
 > $foo
 Loading package array-0.5.0.0 ... linking ... done.
 Loading package deepseq-1.3.0.2 ... linking ... done.
 Loading package containers-0.5.4.0 ... linking ... done.
 Loading package pretty-1.1.1.1 ... linking ... done.
 Loading package template-haskell ... linking ... done.
 unknown package: main
 }}}

 The problem is the last line, failing to find the `main` package. I can
 reproduce this issue in 7.8rc1 and in HEAD.
