That is intentional.  That way the new 'scons check' that runs "ubxtool
-V" shows the broken install.

Before it just gave a crash dump.  Now it gives an informative
error message.

Ditto for "zerk -V"

I can see the need for a SConstruct rule to test for pyserial, the
same way the new tests check for Gtk.

I wanted to do that for a while.  But then I realized people will then
try the serial, fail, and hate us.  Non-trivial fix, but should not be
hard either.

Either way, a warning from scons would also be helpful.
