 Component:  Cabal library  |      Version:  1.14.0    
  Severity:  normal         |     Keywords:

----------------------------+-----------------------------------------------
 The solver determines an install plan that fixes package ids of installed
 packages.

 However, the Setup interface currently does not allow us to specify
 package ids once we start building; we can only fix the versions.

 This can lead to problems in situations where multiple instances of the
 same package version are installed on a system, and the install plan
 selects one, but we cannot uniquely communicate that to the builder.
