08:35 AM version number confusion

[ #7652 ]

cpan> r

Package namespace         installed    latest  in CPAN file
Crypt::RSA::ES::PKCS1v15       1.10       1.9  V/VI/VIPUL/Crypt-RSA-1.46.tar.gz
Crypt::RSA::Key                1.13       1.8  V/VI/VIPUL/Crypt-RSA-1.37.tar.gz
111 installed modules have no parseable version number

So which version do I actually want installed? :)

  • I did this with Win32::ASP, one of my first modules. I got a nice letter from Andreas correcting my usage of version numbers. I suspect he doesn't have time to mail everyone though.

    Basically, perl (or rather treats them as real numbers, not "minor.major", as I was used to. So you probably want x.10, even though CPAN thinks x.9 is newer.

    It's nice to email the author about this, as merlyn has done -- a couple times! -- for me. Point them here [] if they need to use better methods for creating versions from CVS revision tags.
