Re: Package Require getting "wrong version"

As unsolicited advice, I'll note that no good program should contain
[package require http], since that's free to deliver either version 1.0
or version 2.* and of course those interfaces are completely different.
Use the 'requirement' argument(s) of [package require] to ask for the
command set your program actually uses.

I am not sure I follow your suggestion. Would you care to elaborate
on this?

If your program uses the commands provided by http 1.0, use the
command

package require http 1

If your program uses the commands provided by http 2.$N, use the
command

package require http 2.$N

where $N is as small as possible to get all the commands you use.

Omitting the 'requirement' argument(s) is simply a recipe for failure.
