pybuilder help -- why no python3- pkg proper build/tests?

[Yaroslav Halchenko <debian@onerussian.com>]

Dear Debian Pythonistas,

I am trying to make our DataLad package to be bi-python finally, but I
cannot make pybuilder neither populate python3-datalad package, nor
to run tests (using nose) during the build against python3 (runs only
against python2).  It does invoke dh_python3 at the end though...

Here is my current (trimmed, temp state) version of packaging
(rules/control):
https://github.com/yarikoptic/datalad/blob/debian/debian/rules
https://github.com/yarikoptic/datalad/blob/debian/debian/control

and a sample build log:
http://www.onerussian.com/tmp/datalad_0.10.0~rc4+git167-g88f3ea8f-1_amd64.build

I am probably  missing something obvious -- please help me see it ;-)
