 Every time I run {{{cabal install}}}, cabal rebuilds and relinks part of
 my application, because it generates a fresh Paths_package, even though it
 is the same. When overwriting Paths_package Cabal should first check to
 see if the code changes, and if not, not write anything. Example of the
 bug:

 {{{
