That too completed without error. Your RPM was built on a Fedora, RHEL 6, or other more recent OS with the updated version of RPM. I'm afraid you'll have to recompile it to get it to work well: use 'rpm2cpio' to take apart the SRPM and get the files, then deposit them in a relevant "SOURCES" directory with the .spec file in your relevant SPECS directory, and try to rebuild RPM's with the .spec file. I can get into more detail if you need it, but it's how I backported Torque 2.4.10 to RHEL 5 from the EPEL RHEL 6 repository two weeks ago.
