I finally got VPython working on RedHat Linux 6.2.
It appears that there is a bug in the threading support in the
kernel (2.2.14-5) distributed with 6.2. I found that even the
thread examples from glibc would not run. Upgrading libc did not
help, but upgrading the kernel (to 2.2.16-3) got them running.
(These are all standard RH 6.2 updates).
I also had to recompile cvisualmodule.so do that it would link
to the available libstdc++-libc.
That required me to install gcc 2.95.2, as the egcs-2.91.66
that comes with RH6.2 fell over with an internal compiler error.
So finally I have it working on Linux.
(But I have had much fun on Win98 in the meantime).
