It appears that I forgot to run "make distclean" before building that last round of tar.gz and zip files for both Rudiments and SQL Relay. So, if you downloaded last week (the week of October 6th, 2014), or the week before, then you may have had trouble building. Configure probably ran, but make might not have made anything.
Who knows what platform the binaries that were in there ran on? Fedora 20 x64 maybe... Maybe not though.
I just updated the tar.gz and zip files with clean versions. I also downloaded and verified them this time. They ought to be correct.
Thanks Florin... If you hadn't pointed it out, I might never have noticed.
