Netgen error during STEP/IGES import

Hello,

When I try to import any geometry into Netgen I get:

NETGEN/NGSolve V4.4
Developed at Johannes Kepler University Linz, Austria
ERROR: IGES import requires the OpenCascade geometry kernel. Please install OpenCascade as described in the Netgen-website
errinfo: IGES import requires the OpenCascade geometry kernel. Please install OpenCascade as described in the Netgen-website

Any idea why Netgen is not working correctly?

Thanks
JMB

Bump!

Does anybody know why this happens in the CAELinux2008.1 LiveDVD. Has OpenCascade not been compiled in?

Thanks
JMB
