It built fine for me on my MountainLion machine. =(

Could you attach a log of your successful build? Maybe comparing it with mine will reveal some pertinent difference. For easier comparison I'm attaching a new log built without universal or parallel building. If you could do the same for yours that should make our logs most similar:

sudo port -n build webkit-gtk -universal build.jobs=1

I did forget to turn off ccache so that's still in the log but that should be easy enough to account for if you don't use ccache.

[ryandesign (Ryan Carsten Schmidt)]

It seems webkit-gtk has an internal version of google-test, and the failure occurs when the google-test port is already installed and it tries to use that version instead. The attached patch ensures this won't be the case.
