Ray,
I second this method recommended by Hans. I strongly recommend staying away
from putting use statements in all of your components if you run Mason under
mod_perl. This can lead to intermittent bugs due to race conditions if you
forget to put a use statement in a component where the code uses a module.
For example you write component a including a "use CGI" statement and
instanciates a CGI object. Later you work on component b and instanciate a
CGI object. When you test component B it works fine in development because
you've already tested component A which loaded CGI into the embedded perl
runtime. However, when you push code to production or restart the server
you may find that sometimes component B doesn't work. This happens because
you forgot to include a use CGI statement in component B.
Using all of your modules in your mason handler will ensure that you never
have to deal with such a race condition.
I've never used the PerlModule directive before but the mod_perl 2.0
documentation says that it's the equivalent of doing a "require MyModule"
which isn't exactly the same as a use statement. perldoc -f use for
details.
