Can't install on OSX Mavericks

[rzane]

I have Firebird CS-2.5.2-26540-0-lipo-x86_64 installed at /Library/Frameworks/Firebird.framework. Before I upgraded to Mavericks, I had no trouble installing.

Here's mkmf.log:

Solved. For anyone who encounters this issue, just run xcode-select --install and you should be good to go.
