Thanks! Will try it tonight.

I'm just puzzled why entering "valgrind" into the search field of maemo.org didn't return the link you posted. Or let me put it this way: I didn't find an easy way to go to http://maemo.org/packages. Is it linked somewhere?

I only checked "garage.maemo.org" for software

Entering "n900 valgrind" or "maemo valgrind" into google didn't return any useful results, too.
