Here's the background to this question:

Canola2 has a recent update that sucks. People want to go back to the prior version. Or someone flashed his device and now wants to re-install Canola (but with the old version).

Problem: there is no .deb, or at least no repository with all the dependencies, for doing a standard installation.

However, I still have the "good" Canola2 installation on my N800.

The gist of the question:
Is there any way I can "package" what I have to send to other users?

Here's the thread where this problem has arisen:

Then, if you want, you might read #42 thru #49: http://talk.maemo.org/showthread.php?t=33799&page=5

I've specifically stated this with respect to Canola, but it is a problem that could come up again with other programs.
