I'm guessing below, because I can't find the source of the "binary
driver" you are discussing.  The bug report doesn't point to it, and
it isn't in an obvious place in the OLPC git or the Sugar gitorious.

It's not a "binary driver", it's just a library implemented in C or C++
rather than Python.  This is only novel to the Sugar team -- the vast
majority of packages in every Linux distro are already this way.

There's already a python-alsaaudio package in Ubuntu:


If this is the module you're calling, your sugar-measure-activity
package just has to mention that as a dependency, and all should be

If you have your own unique python-alsaaudio module, you'll probably
want to merge it with the already-existing one, and fix up Measure
so it can call the existing public one.
