Hi, (The message below contains bunch of "preformatted" sections. I hope it's still readable, otherwise, please, let me know.) My quest is to install lambdabot (for the sake of offline `@hoogle' and `@pl' commands), and the one depends on `plugins'. 1) plugins.cabal should be updated ---------------------------------- A patch to .cabal file[1] is needed to get rid of config-time warning[2] and resolve build-time errors[3].
