It's possible that your copy of perl is somehow enabling tainting
checks before it runs.  Running perl with the '-T' switch enables
tainting checks.  These checks are usually used for security reasons,
and one effect is to remove the current directory from the include
path.

I'm not much of an expert either.  Maybe something at
http://perldoc.perl.org/perlsec.html will help.

Is mythfrontend or the mythweather plugin set to run with setuid or setgid?
