Permission error after installing "pyechonest"

I'm facing a permission problem while I'm using "echonest" plugin under Debian Squeeze (Python 2.6).

-rwx------ 1 root staff 11 Jun 12 13:51 /usr/local/lib/python2.6/dist-packages/pyechonest-8.0.0.egg-info/top_level.txt

Fixed by chmoding to 664:
$ sudo chmod 664 /usr/local/lib/python2.6/dist-packages/pyechonest-8.0.0.egg-info/top_level.txt

I hope it helps :)
