fancy you ;) it would cost you though:  pybuild is relatively new and
not available on elderly ubuntus (there is a backport for debian stable
wheezy so there we all set).  But if you do not care -- me neither twice
;)

easy one, just symlink to sid

$> ls -l /usr/share/debootstrap/scripts/jessie
lrwxrwxrwx 1 root root 3 Jul 14  2013 /usr/share/debootstrap/scripts/jessie -> sid

forget about squeeze -- oldstable, and no pybuild anyways ;)

hm - interesting if I got it right (too late now to think straight... even sent
out a google recruiter to f.ck off (politely)) you are claiming that in your
local environment (which is?) pybuild results in a different behavior than
while building in those clean chroots?

I am not yet using pybuild much myself, did for one package, let's see
since recently I have packaged (not yet uploaded) a little package, my
debian/rules was:

$> cat debian/rules
#!/usr/bin/make -f
 
DH_VERBOSE=1

export PYBUILD_NAME=husl

%:
    dh $@ --with python2,python3 --buildsystem=pybuild


and I had not debian/*install files at all

during debian/rules install

it built into .pybuild/ and then placed them into corresponding 'fakeroot's
right away, without going to debian/tmp, which is indeed usually a default
target for installation and then dh_install (using debian/*.install) sorts
those files into per-package directories.

so the most productive would be if you just place your packaging into a git
repository (better make a separate branch, e.g. debian which would sit on top
of releases and contain only additional content under debian/ directory, see
e.g. my pandas or anything else on github).  let me know where it is and
I would have a look.  First step would be to make sure it builds in a
clean debian sid chroot/pbuild/cow environment (nd_build4debianmain).
