John,
What distribution are you trying to install this on? I'm guessing it is not an rpm based distribution, and I'm guessing since your previous distribution was Slackware you are probably still using Slackware.
The problem is that even if you install rpm in Slackware, the rpm database is not populated with all of the components in your system. There is a nice howto on
installing NI-DAQmx 8.0 on Slackware 10.2, that will probably help you get started. Even though it is for written for NI-DAQmx, it should be relevent for NI-488.2 or any of our drivers.
