Can you provide more detail on this? We'd really like the shared webmin recipe 
to work properly, if there's an issue we should try to fix it there.

Can you please paste in the exact message?

PREFERRED_VERSION is the correct way to do this. The proper place to set 
PREFERRED_VERSION_webmin would be in your custom distro config (assuming you 
have one - which you really should if you are doing anything more than 
experimenting.)
