As a followup to my previous posting: I have these versions of ORBit installed: [phil at unagi phil]$ sudo rpm -qa | grep ORBit ORBit-devel-0.5.17-10.3 ORBit2-2.7.5-5 ORBit-0.5.17-10.3 ORBit2-devel-2.7.5-5 It looks like a configure error. Has anyone on this list built this successfully on RedHat 9 or Severn? Cheers, Phil
