Unable To Apply Oracle Portal 11g Patches Using OPatch Getting Too Many Arguments And OS Undefined Variable (Doc ID 1465506.1)

Error 1:
=======
opatch: line 386: [: too many arguments
- This is caused by using the double quotes " " in the opatch command. The readme incorrectly has these around the -pre section and they should not be there.

Error 2:
========

Please set your ORACLE_HOME to your 10.1.2 midtier installation home.

OS: Undefined variable.

Command invocation returned Error... 'OS: Undefined variable.
', Return Code = 1

- This is caused by a few issues. Ensure you have the latest 11.1.0.0.0 OPatch version downloaded, and ensure you have the Mandatory Portal 11g Patching Patch which fixes issues with the patching tool itself. 
Reference: Note 1443292.1 Recommended Patches for Oracle Portal 11g
