Attached is the output from make.
I have since successfully installed, recompiled, and run kernel-2.4.9-6 from RedHat. The nigpib-0.8.1 code compiled successfully with 2.4.9 installed. I then went and removed 2.4.9 and reinstalled 2.4.2. 2.4.2 reinstalled, recompiled, and ran successfully, and the nigpib-0.8.1 was broken again.
