To summarize issues raised in this ticket: 1. Parrot::Configure::runstep() has been renamed Parrot::Configure::run_single_step().
2. Additional tests have been written for it is quite high (http://thenceforward.net/parrot/coverage/configure-build/lib-Parrot-Configure-pm.html) -- but not yet perfect. 3. The functionality for re-running a particular configuration step (e.g., for regenerating a Makefile between configuration and build) has been moved to tools/dev/reconfigure.pl. This is the sole location where, to my knowledge, run_single_step() is invoked. 4. Discussion of file-based configuration has been moved to https://rt.perl.org/rt3/Ticket/Display.html?id=44315. 5. Since run_single_step() is post-configuration functionality, it doesn't truly belong (IMHO) in a package devoted to configuration per se. Just as I proposed (and implemented) a distinction between the locations in which configuration options processing and post-configuration options processing are found, I intend to develop a patch which would move run_single_step() out of Parrot::Configure and into a class devoted to post-configuration reprocessing. But that's a subject for a different RT ticket. I'm sick of looking at this ticket and am closing it now. kid51
