Not true. My main machine is Mac but several other developers use
Linux. We also perform nightly testing on a variety of Linux
platforms. Having said that, I am not sure how well loading a plugin
from Python is tested. I am guessing your problem is going to be some
shared library dependency and the way Linux resolves shared libraries.
I am not an expert on shared library loading so I can't help much...
