Hi, this looks like a Proj version mismatch (Proj compiled into Therion trying to open a database belonging to another version of Proj installed in the system). Check if Proj command line utilities work (run e.g. "projinfo EPSG:32634"), check the version and check if the version matches the version of Proj used in Therion.
 

Today’s successful compilation of last snapshot on MacOSX 10.13.6.

This is part of compilation where is version of proj used. Project is listed in lines 91-218 of compilation log.
