Has anyone managed to install pyserial for Python3?

pyserial isn't one of the packages listed by opkg.

When trying to build from the source (http://pythonhosted.org/pyserial/pyserial.html and https://pypi.python.org/pypi/pyserial) I get an error:
"unable to open /usr/lib/python3.4/config-3.4/Makefile"; sure enough, the whole config-3.4 directory is missing after a python3-light install.
I'm unfamiliar enough with the python packages to know why.

(note: the soureforge link above is just for Python 2.7 and before, and is a bit dated).

Thanks in advance,
Bill
