Failed to find python headers during compile

Hi all sorta new to OpenWRT but we are trying to use it to handle some authentication using freeradius and its python module. Only problem is the python module doesn't exist as a package to be installed so we are trying to compile it ourselves. I am able to compile everything fine from the normal package feed, its just adding the module results in this error:

The altered package makefile is here:

I have tried a few different permutations based on other makefiles that use python but they all fail with the same error above. I have python-dev installed and if I run .configure in the freeradius folder it finds the python headers just fine though my belief is that it looks for the headers elsewhere during the compilation step.

The headers are in the location it is looking so I am not sure why it is failing
