Comment:

 I got
 {{{
 $ cabal install
 Resolving dependencies...
 Configuring alsa-core-0.5.0.1...
 cabal: parsing output of pkg-config --modversion failed
 cabal: Error: some packages failed to install:
 alsa-core-0.5.0.1 failed during the configure step. The exception was:
 ExitFailure 1
 }}}
 because
 {{{
 $ pkg-config --modversion alsa
 1.0.14a
 }}}
 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.
