6646853 - CPUJAN2008 fails with OUI-67215 stderr of the make command

You are installing database patch# 6646853 - CPUJAN2008 on top of your 10.2.0.3 
OH on OEL-5/Update-1/x86-64(64-bit).  It fails towards the end of installation 
during  relink (make) with the following errors:

cd /copy/download/oracle/CPUJAN2008
unzip p6646853_10203_Linux-x86-64.zip
cd /copy/download/oracle/CPUJAN2008/6646853
$ORACLE_HOME/OPatch/opatch napply -skip_subset -skip_duplicate

There are lots of warning while relinking oracle for "undefined reference" and 
the following errors right before that (you can find the logfile in the 
following directory - $ORACLE_HOME/.patch_storage/6646853*/rac/*.txt ):

Install p5240469_10203_Linux-x86-64.zip (see ML Note:417319.1 for details)
What Note:417319.1 doesn't tell you though is what to do with this problem 
after you've hit it - i.e. do you rollback the patch, or do you just apply 
5240469 and be done with it ...

My recommendation is to completely remove your ORACLE_HOME, restore from a 
backup (you have a backup don't you?), then apply 5240469 and only after it's 
done apply CPUJAN2008 (6646853).
