Starting pam-0.2.0.0 Failed to install pam-0.2.0.0 Build log ( /home/builder/.cabal/logs/ghc-8.6.3/pam-0.2.0.0-1lAxwnixxe0EnbzrCh0GlI.log ): cabal: Entering directory '/tmp/cabal-tmp-22335/pam-0.2.0.0' Configuring pam-0.2.0.0... cabal: Missing dependency on a foreign library: * Missing (or bad) C library: pam 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 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-22335/pam-0.2.0.0' cabal: Error: some packages failed to install: pam-0.2.0.0-1lAxwnixxe0EnbzrCh0GlI failed during the configure step. The exception was: ExitFailure 1
