Oracle/Linux Installation Problems

I am using a Debian GNU/Linux box running the stable distribution.

Installing Oracle is a smooth process with the only error reported being that /usr/local/java does not exist. The error can be ignored and continues until the installer reports that Oracle and all components are installed.

However, when I try to begin a SQL Plus session the following occurs (Spacing for clarity):

tillarium:/home/tilleyrw/OraHome1/bin# dir sql* sqlj sqlldr sqlldrO sqlplus sqlplusO

tillarium:/home/tilleyrw/OraHome1/bin# echo $PATH /sbin:/bin:/usr/sbin:/usr/bin:/usr/bin/X11:/usr/local/sbin:/usr/local/bin:/oracle:/home/tilleyrw/OraHome1/bin

tillarium:/home/tilleyrw/OraHome1/bin# sqlplus Message file sp1<lang>.msb not found
Error 6 initializing SQL*Plus

tillarium:/home/tilleyrw/OraHome1/bin# sqlplusO sqlplusO: error in loading shared libraries: libclntsh.so.8.0: cannot open shared object file: No such file or directory

Can anyone comment on this? Any information leading to a working database would be much appreciated.
