I just thought I'd pipe up and say that while this part of the build
does take an awfully long time, it eventually finishes. I've been
working through build issues with a couple projects on Mac OS X 10.6
all weekend and this one eventually concerned me until I realized it
was just a bit slow.

I can confirm that calling wx:new() throws an error that mentions
undefined symbols. I've pasted it below. I'm not actively using wx but
maybe the trace helps someone somewhere.
