Some reasons I can think of are reducing startup time, avoiding permissions
issues for writing .pyc or .pyo files, and consistency (you're sure all
installs have the same .pyo files).

Should come from the installer right, where else can it come from? No idea
at what point during install though.

Look at the numpy/tools/numpy-macosx-installer/new-create-dmg script and how
it's called from the paver dmg task. If you have an mpkg that should work
with very few changes.
