Oh, I was not clear about this : I'm a linux coder, and I have not yet started 
coding on maemo but intend to do so soon (hence my subscribing to this list). 
Sorry for throwing you on a path harder than it seamed. OTOH, compiling strace 
should not be a problem as it is a very classic Unix tool, available in all 
the distributions for all the platforms. Maybe you can even grab a precompiled 
Debian package and install it.
