 Great, glad everything looks okay! (Apart from the test failures, anyway.)

 version of `cairo` needs to be installed before you can test it:

 there in the deps.


 Ah, great catch. I'll add a pre-test check to ensure the port is already
 installed - and at the same version/revision - to avoid that situation.
