An rpm for i386 Centos 5 has been uploaded using the old Olex2 release and version information. This is to address an issue FH was having. The .debroglie has been dropped off the rpm in-line with fedora, centos, and rpmfusion standards. Don’t be scared!
Olex2 is in a state of flux regarding many things, as such consider the name and versioning issues we are currently experiencing a transient bump in the grand scheme of things. Especially regarding the olex2-gui.
FH I hope this sorts you out.
