All of the C extensions are combined into one library, to get around the Android dlopen() limit. However, this causes issues when you have modules in C extensions with the same name.

For example, if you have two C extensions a and b, and they have modules a.mod and b.mod, the application will not work. Both extensions will produce a file mod.so, and will be copied into the same directory and so one will overwrite the other. I did some testing by putting each package/recipe's output in its own directory, but that has issues as well. The C extension modules have an init function which is not namespaced - it will be called init_mod() in both modules, so the functions overlap when added to the same library.

I'm not really sure what a good fix is for this, I just wanted to make sure that it's a known issue.
