We can't figure out why you're getting that error message.
Can you please send us a few more things such as:
1) what platform are you on?
2) where is your MQ installed on the system?
3) Do you have any mq* or MQ* or JMQ* environment variables set?
4) Send us layout of the top-level install ('ls' of the top-level install dir).
5) Perhaps send us the more output from the log file instead of just that error line.
