We have web.py-0.32 in portage marked unstable. It's just a bunch of python files, nothing to compile or so. It emerges and works correctly on at least amd64, hppa, x86. Please mark that stable and bump webpy to the current upstream stable 0.34, possibly for fast stabilization of that too. The ebuilds will need some slight modification to install >=0.33 due to changes in the source tarball. I will look into that as soon as possible.
One bug per one issues, threating this one as version bump request...
Bumped to 0.34. Filed stabilization request for 0.32 in bug 321431.
