C'mon, I'm not ''that'' dumb! `X-D` But just to be sure, I tried building
& testing again, and I encountered the same errors.
I do think the following output from building is pertinent (slightly
edited for readability):
{{{
setup.py:693: UserWarning: could not find dependency <string> included in
/Applications/sage-4.8.alpha4/local/lib/python/site-
packages/Cython/Includes/libcpp/string.pxd.
I will assume it is a system C/C++ header.
warnings.warn(msg+' I will assume it is a system C/C++ header.')
setup.py:693: UserWarning: could not find dependency <vector> included in

packages/Cython/Includes/libcpp/vector.pxd.
I will assume it is a system C/C++ header.
warnings.warn(msg+' I will assume it is a system C/C++ header.')
}}}
The file referenced is definitely there, and includes a declaration of C
headers. If I inspect the file, I see a declaration of a `cppclass` from
`<string>` that should cover it. Yet, when I run the doctests, I get
boatloads of errors of this sort:

and more just like it.
I suppose it's possible that this installation of sage is simply pooched,
though that would seem very, very weird; other patches go in without a
problem. It's a MacBook Pro running 10.6.8. On my Ubuntu box running sage
4.8.rc0, the installation passes.
I will run the full battery of doctests on the Ubuntu box, and also try a
fresh install of 4.8.rc0 on the MacBook Pro. If it all works out, I'll
give it a positive review.
