There may be a better way but this is how I got it to work on Red Hat 5, RHEL 5.:

1. Download Framework
2. copy the Zend folder under the framework library folde to /opt
3. edit the etc/php.ini file to: include_path = "/opt/"
4. Make sure to uncomment the includ path so it will run, ie take out the semicolin at the begining.
5. restart apache
6. also make sure that error_reporting = E_All
7. and display_errors = On
8. this will help debug
9. save /etc/php.ini
10. restart apache: apachectl restart

I copied the measure example from the api and ran it till I got it worknig.

Don't forget to set your file permissions.

I hope this helps, sorry I did not have time to put the copy commands and everything in here.
