- This variable contains the version of the oldest perl

- search in $sitelib for older directories across major versions
- back to pm_apiversion. This is only useful if you have a perl
- library directory tree structured like the default one. The
- versioned site_perl library was introduced in 5.005, so that's
- the default setting for this variable. It's hard to imagine
- it changing before Perl6. It is included here for symmetry
