Import fails with python but succeeds with python -v

Hi,
 
I've noticed strange behaviour where cx_Oracle will fail to load when
using "python" but it will succeed when using "python -v" while throwing
"Unsatisfied code symbol" errors.
 
This is for Python 2.5, Oracle 9.2 and cx_Oracle 4.3.1 on the platform
HP-UX 11
 
Output for python:
  ImportError: Failed to load cx_Oracle
 
Output for python -v: (extract of the errors)
 
  shl_load
/admin/3rd_party/HP-UX/cx_Oracle-4.3.1_build/build/lib.hp-ux-B.11.23-ia6
4-2.5/cx_Oracle.so
  /usr/lib/hpux32/dld.so: Unsatisfied data symbol 'kpggwcx_' in load
module '/product/app/oracle/9.2.0.2.svr/lib32/libwtc9.so'.
  /usr/lib/hpux32/dld.so: Unsatisfied code symbol 'LhtStrSearch' in load

  /usr/lib/hpux32/dld.so: Unsatisfied code symbol 'kpugdr' in load
module '/product/app/oracle/9.2.0.2.svr/lib32/libwtc9.so'.

I don't really understand why using python -v results in such a
different in behaviour since as far as I know, it's just a verbose
option. 
 
Any help would be appreciated in figuring this out so I can hopefully
apply that knowledge in importing cx_Oracle without using the -v option.
 
Thanks,
John
