[Koha] updating libc6 for koha

[Diederich Hessling]

First of all, as this is my first mail to the list, greetings to everyone out there who reads this. I am a 
student from berlin, at the time trying to set up koha for a befriended library, but before that on my own 
machine.

I have Linux 3.1 (sarge afaik) installed on my pc and am trying to make my way through to getting koha 
work on it.
Problem as follows:

I try to set up NET::Z3950 with the usual makefile etc., this module says it can't find -lwrap.
I've found out that I need libwrap0 installed to solve that.
libwrap0 (and libdbd-mysql-perl as well) say they need the libc 2.3.51 or higher versions of it, whereas 
on my linux installation there is something like 2.2.32. I've read that there is a high chance of messing 
up the system should i try to install libc from newer distributions. I couldnt find libc6 2351, but instead 
2.3.6.7, which is apparently of the unstable-linux-distribution.
though i didn't find relevant postings in the koha archive i assume i am not the first one who has this 
problem and i wanted to ask if and how others have solved this.
You may yet have noticed that i am not an experienced linux user.

thanks in advance and excuse my pidgin english

greetings,

Stefan Gesing
