I followed the standard recipe from the Debian Wiki when I converted the
package, and as it still worked afterwards ... You may well have found a
geniune bug in that the old files are being used instead. We'll see.

No, I basically have zero env.vars set for anything.

That seems very likely:

Ah, you're not dismissed yet :) We first need to get to the bottom of
this. I now feel I really am missing something in the package.
A quick glance reveals that python-numeric has a working postinst in
/var/lib/dpkg/info/python-numeric.postinst:
#!/bin/sh
set -e
# Automatically added by dh_pycentral
if which pycentral >/dev/null 2>&1; then
pycentral pkginstall python-numeric
fi
# End automatically added section
whereas python-rpy doesn't. I may have a leftover flag preventing the
automatic generation of that stub... A quick glance at rpy's debian/rules
show that I do of course call dh_pycentral. Hm. Not quite there yet...
But we'll get there.
Thanks, Dirk
