how to exclude python (test-)modules from byte-compilation with dh_pycentral

[Jonas Meurer <jonas@freesources.org>]

Hello,

At preparing zope2.11.3 packages, I found several python (test-)modules
that do have python2.5/python2.6 code. This code is mostly for checking
python2.5/python2.6 support, and thus isn't relevant for the
functionality of zope itself.

Zope2.11.3 still requires python2.4, so when the package is installed,
python-central exits with a byte-compiling error, see below.

Is there any possiblity to exclude/ignore the modules in question at
byte-compilation time? I found -X for dh_pycentral, but that one doesn't
seem to do what I expected it to do.

Another solution would be to completely remove the test modules in
question, but that would require a lot of work, as at least the
mechanize module (last error) is used in several other test modules of
zope2.11.3, and I don't want to remove all/most test modules after all.

here are the errors I do get:
