Wow, that's almost a year old!  Things have changed a bit since then. :-)
I believe the problem is fixed in the current version--0.8.10.

I will probably release a new version soon.  The new version fixes 
a few bugs and adds deprecation warnings, as well as using 
string exceptions and defining True/False.

Barry added this recently to python mode, so you'll have to wait a bit
(or get from CVS), but M-x compile works.  Then you can do 
'pychecker *.py' for the command (or whatever you want).

The warnings will come up and you can do C-x ` to move to the warnings.

The file is not in the rpms, you can get it here:

http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/*checkout*/pychecker/pychecker/pycheckrc?rev=HEAD&content-type=text/plain

If you want the file from version 0.7.5, change HEAD -> v0_7_5
