I guess I should have been more clear. Our Unix Admin installed the Module and said the test was fine, but when I've tried to develop a program I'm getting errors.
You've still not said whether the test script fails for you. Have you tried it?
If the test script fails then I think you have a good excuse to go back to your sysadmin and ask them to install it properly this time ;-) It really looks like there is a problem with the install to me.
This is why test scripts are great. You know it should work. The sysadmin said it worked at install time. It doesn't work now so you know there is a problem.
If the test script passes and your script fails then you may well have found a bug. In which case submit a bug report.
