[Paraview] Inconsistent results with the stream trace filter

Tue Oct 23 07:18:20 EDT 2012

Thanks for the info Leo,

I am, however, having trouble building the source that I've downloaded.

Could you point me to any instructions on how to build?
http://paraview.org/Wiki/index.php?title=ParaView:Build_And_Install&oldid=46445#On_Unix-like_operating_systems_2doesn't
seem to tie up with the files I get.

These are the files I've pulled from Git:
