Eheh! The culprit on Linux has been found. Whilst playing around with the
dependencies, I had left local copies on the Linux desktop (in the same
place where I was executing the executables). It would appear as though it
used the dlls that were on the desktop instead of the proper 2.0 dlls. So
indeed, a configuration error as you predicted. :S
I deleted the dlls on the desktop, and now it is working. Hopefully it was
just those dlls causing the problem, as I also disabled Input Method Editor
and multi language support.
My Mac environment does not have such an infestation of dlls on the desktop
though, but I'll run through some of the directories to make sure.
.. I cannot believe I made such a noobish mistake, lol.... :(
