I was manually uncompressing the zst but since stap was still not finding it I assumed there was some other bug but there isn't as stap is basing it's search on what it finds in the modules.dep, aka still trying to process the zst version. If I hand edit the modules.dep removing the zst extension systemtap now works. @mliska, can we please fix the above elfutils bug please, in factory and SP4
