Well, I know it looks odd, but I'm not trying to be perverse, on the
contrary. I needed to generate F14 deltarpm binary rpms that use the new
compression, but wanted to use no more than necessary from F15. It's
necessary to use F15's xz packages, obviously, but it turns out that the
F14 deltarpm src package works as long as rpmbuild is run while the F15
xz packages are installed. The "old" and "new" in my directory names
refer to old and new compression, so "deltarpm.old" and "xz.old" contain
the standard F14 binaries. If I take out the first "run" from my script,
here is the output:
