I can actually verify that CPANPLUS doesn't send automated "failure" reports when no Makefile is generated; I tested that locally myself this morning after reading your previous message. > > It'll also mean that automated test reporters like CPANPLUS will stop > > filing "failure" reports when its really the test environment that's > > lacking. > > CPANPLUS is a totally separate distribution that does its own test > reporting. The most common smoker engines use it. That's what I'm finding too; the vast majority of CPAN Testers reports that I see are from CPANPLUS. Although CPAN doesn't support this in a release yet, knowing that doing "exit 0" will at least help keep CPANPLUS from filing false failures is a step in the right direction. :) > > So... would anyone care to fill me in on why we don't have CPAN(PLUS) et > > al. re-running "perl Makefile.PL" after dependencies are installed?

Does it simply install the dependency and then continue, or does it install it and then re-run "perl Makefile.PL"? Or, alternatively, does it just choke outright and abort the build? -- Graham TerMarsch Howling Frog Internet Development, Inc.
