Smokebrew - It is like perlbrew but different
So, I finally got around to doing what I was threatening to do at Copenhagen and got a tool created to automate the building and configuration of perls for CPAN Testing.
It doesn't do the environment tweaking, for instance, to switch between the installed perls.
The goal has been to build, install and configure various versions of perl for CPAN Testing.
The configuration is dealt with by App::SmokeBrew::Plugin's. These are objects that are called by Smokebrew after it has successfully built and installed a particular version of perl. Smokebrew comes with two plugins, Null and CPANPLUS::YACSmoke. The former does no configuration and the latter configures for CPAN Testing with CPANPLUS::YACSmoke.
smokebrew --email firstname.lastname@example.org --builddir /home/tester/build --prefix /home/tester/perls --perlargs "-Dusethreads" --perlargs "-Duse64bitint" --plugin Null --recent --verbose
The above would build "recent" perls which are stable perls from 5.8.9 into directories in /home/tester/perls that will have threads and 64bitinit and it will use the Null plugin to configure those perls, which effective does no configuration.
smokebrew --email email@example.com --builddir /home/tester/build --prefix /home/tester/perls --perlargs "-Dusethreads" --perlargs "-Duse64bitint" --plugin CPANPLUS::YACSmoke --recent --verbose
