> version is still there As you said: librep also installs /usr/bin/rep* and /usr/lib64/librep.so* without version numbers. There is no downgrade path by keeping version numbers in /usr/lib64/rep/. If you want to do testing you have to use different install DESTDIR for that.
Current way to have version number for librep and no version for rep-gtk/sawfish is confusing. Either have version for all or none at all.
