We need an extra Perl module - Quota. To install it, run:
|perl -MCPAN -e shell|
If your Perl executable is not located in /usr/bin/perl you will have to edit the path in the first line of lamdaemon.pl. If you have problems compiling the Perl modules try installing a newer release of your GCC compiler and the "make" application.
Several Linux distributions already include a quota package for Perl.
