Munin and Dreambox DM500HD

I bought DM500HD a few months ago.  Since it's always on, I intended to install munin monitoring on it.  The problem is it does not have Perl bundled.
First I wanted to install Perl (I even tried to install mipsel packages from Debian and it kind of worked), but then I found muninlite which perfectly fit my need.
I developed 2 new plugins to monitor its temperature and fan speed.
