That doesn't really work. You should install Python modules and byte
code into Python's site-packages.

That depends on the installer technology, no? If it has
the notion of a postinstall action, then you should run
compileall.py on all directories where you have placed
Python source.

Doing so is a good idea, as it reduces the size of the
package, and possibly allows to support multiple Python
versions (which all have different byte code format) in
a single package.
