Configuring NetSNMP-0.3.1.0... cabal: Missing dependency on a foreign library: * Missing C library: netsnmp 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. Failed to install NetSNMP-0.3.1.0 cabal: Error: some packages failed to install: NetSNMP-0.3.1.0 failed during the configure step. The exception was: ExitFailure 1
