Comment (by jhpalmieri):
I took a fresh Sage tarball, applied the patch here to the sage spkg, and
then built Sage. Then I ran `./sage --sdist ...`. I got this error:
{{{

This doesn't stop the build, but do we need to worry about it? If not, we
should suppress it.
Also, as mentioned above, I took an existing Sage installation, applied
the patch to devel/sage, and ran `sage --sdist ...`. I got the same error
message. Also, in the existing Sage installation, while
`devel/sage/sage/version.py` was correct,
`devel/sage/build/sage/version.py` was not. `local/lib/python/site-
packages/sage` linked to `build/sage/`, and this is what led to the
incorrect sage-banner that I mentioned earlier. Should the installation
instructions include forcibly relinking `local/lib/.../sage` to the
correct thing, if applying to an existing Sage installation?
