issue with pylucene

Hello all,

This is Atif, and I am new to Lucene, I am trying to install pylucene
however, I am having trouble with make operation. I would appreciate any
help in this matter.

I used svn for downloading pylucene '

I followed installation guide from '

I am using ubuntu 12.04 64 bit bit.

Following is the error I get (in make):
