Package: python-lxml
Version: 3.4.2-1
Severity: normal
Now installing build-depends on a development box would remove cython. I found
in changelog a note from 6 years ago I guess for that reason:
lxml (2.1.4-1) unstable; urgency=low
* New upstream version.
* Remove the build dependency on cython, because cython doesn't have
support for python debug builds.

but now we do have cython-dbg so python-dbg I believe should be supported
> python-dbg -c 'import Cython; print Cython'
<module 'Cython' from '/usr/lib/python2.7/dist-packages/Cython/__init__.pyc'>

and lxml seems to build fine for me with python-dbg without pyrex but
cython installed:
$> virtualenv --system-site-packages --python=python-dbg venv-pydbg-lxml
Running virtualenv with interpreter /usr/bin/python-dbg
New python executable in venv-pydbg-lxml/bin/python-dbg
