Build error: missing stlpmtx_std symbols

Greetings,

Thanks to this Forum and the patches at http://homepages.cae.wisc.edu/~kraftche/OCC/patches.html I've been able to come pretty far with compiling OpenCASCADE. This is on Debian lenny (testing) with gcc 4.2.1 and libstlport5.1 5.1.4-1. I get stuck when trying to link DRAWEXE:

What is this? Do I need a newer stlport library?

Thanks in advance for any help you can provide.
