If the library is already installed but in a non-standard location then you can use the flags --extra-include-dirs= and --extra-lib-dirs= to specify where it is. cabal: Leaving directory '/tmp/cabal-tmp-7697/haskakafka-1.1.0' cabal: Error: some packages failed to install: haskakafka-1.1.0 failed during the configure step.
