Same error again, but I think I know what the problem was this time. I've added 'python3.4m' to sys_libs in setup.py...which should link it to the extension modules built by setup.py.

I'll report back after this build is complete.

Regarding the comments about Android's broken dlopen...I'm beginning to wonder if an Android device can really be a development/learning platform...even in a simulated Linux filesystem app like the one I am using.

I've seen a few things about bootstrapping(?) other Linux distros from an Android device...it may be time to investigate further in that area.
