[vtkusers] Incompatible library version issue

[Allen Sanderson]

FWIW I found the issue …

When I built VTK with the R version, the VTK-6.1.0-build directory which was used previously without R should have blown away because it got corrupted. As such, the new version got installed into /usr/local/ which and had screwed up compatibility versions. I eventually did blow it away and build it correctly but the libs in /usr/local/ were taking precedence thus a mixed lib versions.

Cheers,

Allen
