Comment 6 for bug 930471

Re: http://powerplant.yoper-linux.org/projects/software-packages/repository/entry/rocketfuel/rrebuild/rrebuild.sh

This is a shell script which uses envvar's. rpmbuild is a program using macros.
You are attempting to impedance match the two name spaces by expanding
macros in a *.spec.

You might make more progress if you write an import (macros -> envvar)
and the equivalent export (envvar -> macros) for whatever configuration
you wish to use.

If the chosen path values are clearly/cleanly mapped, then it doesn't matter
how the *.spec uses macros conventionally, or whether wget in shell instead
of rpmbuild fetches files.

And a clean mapping is easier to debug than reading increasingly complex scripts
and templates and configuration driving a build process.
