Developer releases use non numeric characters in release numbers, like Business-OnlinePayment-3.00_09.
They're released to be tested.
If you visit http://search.cpan.org/~ivan/Business-OnlinePayment-3.00_09/ you will see in red
** DEVELOPER RELEASE **.
cpan install Business::OnlinePayment nor cpanp i Business::OnlinePayment will not install a development release. | [reply] [Watch: Dir/Any] [d/l] [select] |
In addition to what the friendly unnamed person said above, I install the older version like so:
cpan IVAN/Business-OnlinePayment-AuthorizeNet-3.15.tar.gz
This works as long as the older version is still on CPAN. Otherwise you'd have to go to BackPAN, but I've never needed to do that. | [reply] [Watch: Dir/Any] [d/l] |
