  * status:  assigned => closed
  * resolution:  => fixed


Comment:

 This should not occur anymore since #19737 is fixed.

 However, there remains the upstream bug that cabal checks for
 functionality of all the tools it detects, even if they are not needed.
 If any of the tools are broken, cabal's configuration pass crashes.
