Looks like problem is caused by user agent set by urlib.

Next request works:
curl -L -o /dev/null -v http://jamwt.com/diesel/diesel-3.0.16.tar.gz

This one doesn't work:
curl -H "User-Agent: Python-urllib" -v http://jamwt.com/diesel/diesel-3.0.16.tar.gz

This is still a problem by the way. Uploading a new package to pypi would also fix it, as pypi only has version 3.0.5

#89 looks relevant to this issue

Should be fixed now that release are hosted on github.
