Yay, I now have the sudoers line reduced to this: stowpan ALL=(ALL) NOPASSWD: /usr/bin/stow -d /usr/local/stow cpan The following is not for the faint of heart. The process of setting-up on an existing box is pretty tricky and involves trolling through the .packlists (which are incomplete for e.g. XML::SAX.) See the utils/ directory in the repository (make a backup!) It's not strictly necessary to clean-out your /usr/local[bin|man|lib|share], but mine is now entirely symlinks :-) A further challenge for making this consumer-friendly is that the default CPAN.pm with many distributions doesn't have support for the make|build_install_make|build_command options. So, making an out-of-the-box setup scheme requires possibly shipping a CPAN.pm upgrade in-the-box? I'm not pleased with the dirty DESTDIR trick being played by the wrapper, but `make install PREFIX=...` is ignored, which means PREFIX/--prefix would have to be in the make|build_install_arg of the cpan config and the wrapper would then be really thin. (Yes, it needs to be 'prefix' and not install_base -- stow is *all about* the prefix thing.) The wrapper is: http://scratchcomputing.com/svn/stowpan/trunk/bin/stowpin Notes adduser --disabled-password --gecos '' stowpan mkdir /usr/local/stow/cpan/ chown stowpan:stowpan /usr/local/stow/cpan/ chmod g+w /usr/local/stow/cpan/ The g+w is optional, but you might want a maintainers group to be able to install by hand (though they will have to set PREFIX/--prefix.) $ grep 'install\|stow\|MB' ~stowpan/.cpan/CPAN/MyConfig.pm 'build_dir' => q[/home/stowpan/build], 'cpan_home' => q[/home/stowpan/cpan], 'histfile' => q[/home/stowpan/cpan/histfile], 'keep_source_where' => q[/home/stowpan/sources], 'make_install_arg' => q[], 'make_install_make_command' => q[/usr/local/bin/stowpin make], 'mbuild_install_arg' => q[], 'mbuild_install_build_command' => q[/usr/local/bin/stowpin Build], 'prefer_installer' => q[MB], Then (assuming proper permissions for your user) su - stowpan /usr/bin/cpan Foo::Bar --Eric -- The reasonable man adapts himself to the world; the unreasonable man persists in trying to adapt the world to himself.
