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 '
http://svn.apache.org/repos/asf/lucene/pylucene/trunk'

I followed installation guide from '
http://lucene.apache.org/pylucene/install.html'

I am using ubuntu 12.04 64 bit bit.

Following is the error I get (in make):

Exception in thread "main" java.lang.UnsupportedClassVersionError:
