I've never used Mason myself, but it looks like your problem is that Catalyst 
can't determine the correct home directory for your app.  You can tell what Cat 
thinks your home is by leaving -Debug mode enabled and watching the startup 
output from Apache:
[catalyst] [debug] Found home "..."

Your template will then be searched for as $home/root/testing.mas

You might need to make sure you have a Makefile.PL file in your app's home 
directory.  It's used when in mod_perl mode so Cat can find the proper home dir.
