I've encountered some errors while installing RRD-MA component.

i'm trying to install the perfSONAR-MDM-3.1 on my computer(Debian 4.0).

by reference to "Admin guide"(perfSONAR-MDM-3.1_Admin_guide_1.5.pdf), i was 
cruising on install. There was some overlapped commands on prepare to install 
each component.(editting /etc/apt/sources.list, install jdk, etc..)

i tried these NOT WORKING commands

"apt-get install librrd2"
"apt-get install rrdjtool"
or so.

even a tiny solution, your reply will be very helpful for me. thanx. :)
