just in case this is not obvious:
travis-ci already features OSX builders, and being a continuous
integration system, these builders already come with a compiler.
so - in the case of travis-ci - there is no need to manually install xcode.

i'd second that, but bear in mind that in this means that you will
actually *build* the libraries (most of the times).
in a CI (like travis-ci) this can lead to timeout problems: whenever a
build is triggered, it starts from a pristine image. so all the
dependencies need to be rebuilt, whenever a build of the main
application(/library/external) is triggered.
with a complex system (like Gem), i keep getting failed builds, because
building the dependencies leaves little time to actually build Gem.
however, you could download arbitrary (prebuilt) binaries, rather than
build everything from scratch.
