What > we can do then, is to generate the expected cmd line on the fly - just like I guess we could go with ^this, but why do we have to "mock" it this way just to let configure pass if this is a build requirement? To me it looks like we're making it unnecessarily complex. Speaking of build requirements, what is your opinion on adding (well goes the same for TC apparently) BuildRequires with mdevctl to the SPEC file? Erik
