[vtk-developers] VTK + Python + AMD64 = broken

[Mathieu Malaterre]

done:

$ cvs ci -m"BUG: RTLD_GLOBAL is still required on AMD64 platform,
since dl module is missing, use an API equivalent one intead: DLFCN"
__init__.py
/cvsroot/VTK/VTK/Wrapping/Python/vtk/__init__.py,v  <--  __init__.py
new revision: 1.14; previous revision: 1.13

this bug is really nasty, I wish I knew a way to reproduce it easily
instead of segfaulting in some random part of the C++ code...

Thanks
