  Reporter:  duncan         |        Owner:         
      Type:  defect         |       Status:  new    
  Priority:  low            |    Milestone:         
 Component:  Cabal library  |      Version:
  Severity:  normal         |     Keywords:         
Difficulty:  normal         |   Ghcversion:  6.10.4 
  Platform:  Linux          |  
Changes (by guest):

  * ghcversion:  6.4.2 => 6.10.4
  * version: =>


 I got
 $ cabal install

 cabal: parsing output of pkg-config --modversion failed
 cabal: Error: some packages failed to install:
 alsa-core- failed during the configure step. The exception was:
 ExitFailure 1
 $ pkg-config --modversion alsa
 I remember that Cabal had functions for parsing version numbers with tags,
 would this help here?
 Newer ALSA versions do not seem to have the version tag anymore.
