Installed mtl-2.2.1 Configuring nanomsg-haskell-0.2.3... cabal: Missing dependency on a foreign library: * Missing (or bad) header file: nanomsg/nn.h * Missing C library: nanomsg This problem can usually be solved by installing the system package that provides this library (you may need the "-dev" version). 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 header 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. Failed to install nanomsg-haskell-0.2.3 cabal: Error: some packages failed to install: continuum-client-0.1.0.0 depends on nanomsg-haskell-0.2.3 which failed to install. nanomsg-haskell-0.2.3 failed during the configure step.
