[Module::Build] Buglet: Creative use of $VERSION confuses M::B

[Johan V. <jvr...@sq...>]

The following sequence of statements (copied from Config::IniFiles
2.38) confuses the version number detection:

    package Config::IniFiles;
    $Config::IniFiles::VERSION = (qw($Revision: 2.38 $))[1];
    require 5.004;
    use strict;
    # Eliminate annoying warnings
    if ($^W) {
        $Config::IniFiles::VERSION = $Config::IniFiles::VERSION;
    }

This causes the following message:

    Package 'Config::IniFiles' already declared with version '2.38'
    ignoring new version ''.
