When starting MailCatcher on Ubuntu, the following error is displayed:

Illegal option -s
Usage: /usr/bin/which [-a] args

I believe this is because you're trying to use a BSD specific argument, which throws an error on GNU which. It appears they had the same issue with Homebrew - https://github.com/mxcl/homebrew/issues/8801

I think the end solution was to implement this - https://github.com/adamv/homebrew/commit/dd280b935c3db50770f58de89029ce6ff6f28218 - so perhaps a similar method is required in MailCatcher?
