[Therion] Loch fails on Fedora 30

[Bill Gee]

Hi James -

I have exactly the same version of mesa-libGL as you mention below.  Below is what rpm -qi has to say about it.

I see that I have both 32-bit and 64-bit packages installed.  Is it possible that Loch is getting confused about which to use?  Answering my own question:  I tried Loch on a VirtualBox machine that runs 32-bit Fedora 30.  Same error.

I rarely use Loch, so figuring out when it stopped working is an exercise in futility.  About the best I can say is it was probably working late last year (2018).  I know it worked at one time ...  Having a working Loch is one of the reasons I switched to using your copr packages instead of compiling from source.  In all the years I compiled Therion from source, I always had to turn off the Loch component because it would always fail.  I was excited to have it finally work!  :-)

Regards - Bill Gee
