0.8.0 was not fully working with 2.7, some fixes went into trunk after the
release. please use a recent svn checkout.

I have gcc 4.2.1 installed (through Xcode), although the build process seems

This doesn't extend but overrides the build flags, that's how distutils
works. With numscons this should work as advertised (although it looks like
numscons has some issue with 2.7 ATM). I've just added a warning that
describes this better at http://www.scipy.org/Installing_SciPy/Mac_OS_X,
because people keep running into this issue.

I'd go with 2.6 for now, that's properly tested and binaries are available.
Any 2.7 issues should be worked out soon, but at the moment YMMV.

Sorry for the very slow reply.
