 Replying to [comment:2 duncan]:

 True.  (I did not.)  But phrasing it as "pkg-config --modversion" gives
 the user the hint that it's an executable (with a man page).  The long
 version would have pointed me in the right direction too.  Either way, I
 think it's worthwhile to cite the exact command Cabal ran.  This gives the
 user a starting place for troubleshooting if there is a problem with the
 user's system installation or they're on an unusual platform, eg.
