Can't find pyconfig.h with python3


Hi all - 

I'm trying to build an OS with a custom recipe ( I can build it as-is in the link above, but when actually trying to use the output of the recipe ( I get the below error in python3: 
>>> import Poverty Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: /usr/bin/ undefined symbol: _ZN5boost6python6detail11init_moduleEPKcPFvvE

I think that's because I built against python2 in some places. So I replaced essentially all of the python dependencies with their corresponding python3 dependencies, but that gives a build error in bitbake like:  
| /local/d6/easmith5/rocko_bitbake/poky/build/tmp/work/aarch64-poky-linux/opc-ua-server-gfex/1.0+gitAUTOINC+921c563309-r0/recipe-sysroot/usr/include/boost/python/detail/wrap_python.hpp:50:11: fatal error: pyconfig.h: No such file or directory
|  # include <pyconfig.h>
|            ^~~~~~~~~~~~
| compilation terminated.

However, I checked and the offending file pyconfig.h is actually present at | /local/d6/easmith5/rocko_bitbake/poky/build/tmp/work/aarch64-poky-linux/opc-ua-server-gfex/1.0+gitAUTOINC+921c563309-r0/recipe-sysroot/usr/include/python3.5m/. When I build with python2 dependencies the file is in the same location, just /python2.7/.

I can't quite tell if this is a yocto problem, or a problem with my recipe and/or build files for that recipe. If anyone has suggestions they would be much appreciated!
