Yocto setup.py requires pyserial

I am trying to package https://github.com/kliment/Printrun in a Yocto recipe but cannot get it working. My recipe currently looks as follows:

LICENSE = "AGPLv3"
LIC_FILES_CHKSUM = "file://COPYING;md5=d32239bcb673463ab874e80d47fae504"

PV = "2.7"
SRCREV = "0193a9dbe31458c45059bf2dcb0a9905b7bb06fc"
SRC_URI = "git://github.com/kliment/Printrun.git;protocol=git;branch=master"

RDEPENDS_${PN} = "python-cython \
                  python-pyserial \
"

S = "${WORKDIR}/git"

inherit distutils

I am assuming this is what I need to do because it has a setup.py that inherits from distutils? If so, this does not work and I get an error complaining about a lack of the serial module:

DEBUG: Executing shell function do_compile
WARNING: Failed to cythonize: No module named Cython.Build

I would also like to be able to compile the small cythonable module with cython. For some reason both cython and psyerial are not availible even though I added them as rdepends, what am I doing wrong?

You added dependency on python cython only on runtime. I guess you need to add also for compilation. 

DEPENDS_${PN} = "python-cython \
                  python-pyserial"
