Hi Biopython community,

I am trying to install biopython onto my mac osx (10.7.4) but after downloading the biopython 1.59.tar.gz from http://biopython.org/wiki/Download and installation get some error which is pasted below.

$cd biopython-1.59
$sudo python setup.py install

It works until it gets to this error and aborts. Could anyone please let me know what is wrong ?

Thanks and appreciate your help. Below is the report, have cut out (......) the middle and have  shown the start and the end output only.
