linux machine without X-server

[GoogleCodeExporter]

What steps will reproduce the problem?
1. execute 
python  svnplot.py -v --dpi 70 -p svnplot-long.tmpl -n "irk" irk.sql ../svn
on Linux machine without X-server

What is the expected output? What do you see instead?
Expected: generated png and htm files in ../svn directory
Instead I see:
Calculating subversion stat graphs
Subversion log database : irk.sql
Graphs will generated in : ../svn
Repository Name : irk
Search path inside repository : /%
Graph thumbnail size : 100
Maximum dir count: 10
using template : svnplot-long.tmpl
Set the search path to /

svnplot-js is now available in trunk. svnplot-js generates plots as 'client 
side' java script and donot have dependency on matplotlib or numpy.
