homebrew is what many of us use to install code packages on OSX.

mistym (Misty De Meo) is a frequent hanger outer in #code4lib, and has 
helped many of us with stuff (including homebrew). She's also one of the 
homebrew maintainers.

Here's a kickstarter from mistym, to help homebrew with some automated 
testing infrastructure, to better handle user code submissions.

It's notable that they're asking for money for actual equipment, not 
developer time reimbursement or anything. They're not asking for much.

Consider kicking in some bucks if you feel like it!
