pip throws IndexError when it calls scraped_rel_links

[combacsa]

When I "pip install supervisor", it succeeds with error message below.

Exception in thread Thread-1:
Traceback (most recent call last):
File "/usr/lib/python2.7/threading.py", line 552, in bootstrap_inner

I'm using Ubuntu 11.04-desktop-amd64 distribution on Intel i5 CPU.

Any ideas?

It is really a bug, and it bothers me. Fixing now.

Thank you
