Notice that the reason the cc command failed is that "sys/types.h" could
not be found.  This probably means you're on a system that lacks a full
"development environment".  As it seems you're on Ubuntu, a convenient
way to get a lot of the requirements for PyPy is probably this command,
run as root:

    apt-get build-dep python2.5

This is because a lot of the build dependencies of PyPy and CPython
overlap.  This won't necessarily give you everything you need to do
everything with PyPy (for example, it won't install libgc or libgc-dev,
which is needed in order for a boehm-based transation to work) but it's
probably a good start.

I think this is a perfectly fine question for this list. :)
