Bad MD5 hash for Lamson package.

edit

I have a fail on install over a debian server using pip. The problem is:

Downloading/unpacking Lamson (from askbot)
  Downloading lamson-1.1.tar.gz (731Kb): 683Kb downloaded
  MD5 hash of the package http://pypi.python.org/packages/source/l/lamson/lamson-1.1.tar.gz#md5=a5673d0fe9e8def9d2dfe9705f832a83 (from http://pypi.python.org/simple/lamson/) (db764749a460c835a45889aa5d242eac) doesn't match the expected hash a5673d0fe9e8def9d2dfe9705f832a83!
Bad MD5 hash for package http://pypi.python.org/packages/source/l/lamson/lamson-1.1.tar.gz#md5=a5673d0fe9e8def9d2dfe9705f832a83 (from http://pypi.python.org/simple/lamson/)

are the installation files broken?

UPDATE: solved using "easy_install lamson" and retrying the command pip
