Oracle.pmod should not be dumped. It depends on external factors such
as ORACLE_HOME and LD_LIBRARY_PATH.
If Oracle.pmod is dumped when these external factors are unavailable,
it is a extremely tricky for our customers/consultants to figure out
that they're supposed to remove the file Oracle.pmod.o to get things
working at all.
