Unless you set POPFile's environment variables, POPFile expects to find its modules and files relative to the directory that you run POPFile from. That means you must either run POPFile from its install directory or set the appropriate environment variables to tell POPFile where to find its stuff, e.g.,
**This works without environment variables set** <code> cd /usr/home/brad/popfile/ perl popfile.pl
set POPFILE_USER=/usr/home/brad/popfile/ set POPFILE_ROOT=/usr/home/brad/popfile/ cd /usr/home/brad/ perl /usr/home/brad/popfile/popfile.pl
</code>
