.mk file for 11g upgrade

Migrating to Oracle 11gr3 and trying to recompile all C code. Using the /sdk/demo/demo_proc_ic.mk and receive the following error:

hall@produpgrade/prod:$cat compile_ag300.log
rm -rf SunWS_cachea
rm -rf /opt/oracle/11gr3/lib/libclntsh.so
*** Error code 2
make: Fatal error: Command failed for target `cleancache'

make file looks like this:
