Created attachment 349765 [details] proposed fix Description of problem: Rules for buliding on ARM are missing.
Problem is obsolete with 1.2.3rc2, which uses the native linux sg interface rather than the package cdrtools library. Are you sure this is about rawhide ?
ok, my bad. It built fine with 1.2.3rc2 http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=44197
