I had not included the haskell library in the package before in binary form, because I was targeting only option A, where it's cloned from the git archive in the package. Any other installation method than the debian package that I know of installs both the propellor command and the propellor haskell library. (Note that propellor 3.0.1^W3.0.3 fixes an unrelated bug that prevented option B from working.) """]]
