Are you building in parallel? If so, try not building in parallel, i.e. using

sudo port install py35-pyobjc-cocoa build.jobs=1

Clang can take more memory than gcc-4.2 did, sometimes a lot more, and this may have been worse with the old versions of Clang you'll find on 10.7.

If it's taking more memory than you have physically installed in the machine, that will result in swapping, which will be very slow, so if you can limit the number of clang processes being started, by not building in parallel, that could end up being faster than building in parallel but swapping.
