The problem occurred after I tried to install matplotlib from source-install.
Any command I try, will give me the error: while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory.
Zypper, LDD, Sudo all provided the same error.
Can't open any logs without sudo...
The find command doesn't find the file but it does reside in the /usr/lib, nothing in /usr/local.lib

Currently running SLES11 SP3.
I will be downloading the Install medium tonight and will try the repair option with the DVD.

Any suggestion to what else I can try?

thank you for taking the time to read this post.
