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.If the library file does exist, it may contain errors that are caught by the C compiler at the preprocessing stage. In this case you can re-run configure with the verbosity flag -v3 to see the error messages. cabal: Leaving directory '/tmp/cabal-tmp-13703/pulse-simple-0.1.14' Starting void-0.7.3 Building void-0.7.3 Completed void-0.7.3 Completed transformers-compat-0.6.6 Completed base-orphans-0.8.4 Completed primitive-0.7.1.0 cabal: Error: some packages failed to install: pipes-pulse-simple-0.1.0.0-4vYdkQ0Og9REPdS72RGvwz depends on pipes-pulse-simple-0.1.0.0 which failed to install. pulse-simple-0.1.14-Br4B8hRfPdS32xtPVj8eUK failed during the configure step.
