[zeromq-dev] Problem installing python language binding on openwrt

Unfortunately, no compiler is available on OpenWRT platform. All the C
packages can be cross compiled with OpenWRT toolchain on another platform.
I have zeromq library crosscompiled and installed on OpenWRT. It was tested
on my hardware with test programs and it works.
Now I only need to install Python binding on OpenWRT in order to use zeromq
library from Python programs. As far as I understand, Python binding is not
pure Python and needs other C/C++ code to be compiled for successful
installation. Can somebody specify which parts I should crosscompile for
Python binding? Which changes needed in setup.py script to have everything
installed correctly?
