Unable to start Oracle Instance via "dbstart"

Question

I've successfully loaded Oracle 11g on a Red Hat Enterprise Linux 5.3. I'm now trying to start the instance and database using the "dbstart". The command does not start the instance successfully or the database. I've pasted the results from the log below:
/opt/oracle/product/11.1.0/db_1/bin/dbstart: Starting up database "TestDB"
Sun Jul 12 16:07:22 EDT 2009
Error 6 initializing SQL*Plus
Message file sp1<lang>.msb not found
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory
/opt/oracle/product/11.1.0/db_1/bin/dbstart: line 113: [: 11: unary operator expected
logger: No init file found for Database instance "TestDB".
logger: Error: Database instance "TestDB" NOT started.
I've been researching this all weekend and have not found a solution yet. Please point me in the right direction for a solution.
My oratab file contains the path of the TestDB and is set to "Y". My profile is as follows:
ORACLE_OWNER="oracle"
ORACLE_HOME="/opt/oracle/product/11.1.0/db_1"
ORACLE_HOME_LISTNER=$ORACLE_HOME
Thanks
