Subject:

Shadowed By the Core Version

Dear John Peacock, Hi. This is imacat from Taiwan. I found that your version-0.7702 was shadowed from the core version 0.77 supplied by Perl 5.10.1 when installed with Module::Build. As a result, the installation of version 0.7702 is unusable. imacat@rinse perl/5.10.1 % find -name version.pm ./lib/5.10.1/version.pm ./lib/site_perl/5.10.1/x86_64-linux-thread-multi-ld/version.pm imacat@rinse perl/5.10.1 % grep '$VERSION = ' ./lib/5.10.1/version.pm ./lib/site_perl/5.10.1/x86_64-linux-thread-multi-ld/version.pm ./lib/5.10.1/version.pm:$VERSION = 0.77; ./lib/site_perl/5.10.1/x86_64-linux-thread-multi-ld/version.pm:$VERSION = '0.7702'; ./lib/site_perl/5.10.1/x86_64-linux-thread-multi-ld/version.pm:$VERSION = eval $VERSION; imacat@rinse perl/5.10.1 % ./bin/perl -mversion -e'print $version::VERSION;'; echo 0.77 imacat@rinse perl/5.10.1 % I tried to make a simple patch in the hope that it helps. Please tell me if you need any more information, or if I could be of any help.

Both 0.7701 and 0.7702 are not releases that have any bearing on 0.77, which was included in 5.10.1 (from the README): Show quoted text

Just because an upgrade was released on CPAN doesn't mean it has to be installed everywhere; that's why I write the README file. I suppose now I should release 0.7703 and tweak the Makefile.PL and Build.PL to refuse to install it on Perl 5.10.1, just for the people who don't bother to read the module documentation before installing. But frankly, I don't have the time and I really don't care enough. John

Yes, I did not read the README. I installed version 0.7702 via another meta command: the CPAN shell "upgrade" command, in order to keep the system current: http://search.cpan.org/dist/CPAN/lib/CPAN.pm#upgrade_[Module|/Regex/]... It's not possible for me to read the README of all 287 modules in my Perl installation when running schedule upgrades. I believe that's how most system administrators do: They upgrade their packages with package managers without reading the README of everything. For this reason, I suppose modules should be friendly to automatic installation and maintenance procedures like the CPAN or CPANPLUS shells. By the way, I suppose 0.77_02 should be used instead of 0.7702 if you are distributing some versions that are not for the public, in order for the CPAN and CPANPLUS shell to skip them. Though I suppose you already know that.
