Hi Monks,

I am working on several web scripts, most of which also use some perl modules I wrote. Because the scripts are heavily used, I keep a "production" copy and a "developement" copy of each one. Due to some new work going on, I now need to start making changes to the modules as well. I don't want to goof up a module and have it impact my users, so I thought perhaps I could get away with something like this at the begining of each of the scripts: 
my $version = '7.54beta1'; #if this were production, it would simply b
+e '7.54'

if ($version =~ /beta/){
    use lib('/path/to/development/copies/of/modules');
} else {
    use lib('/path/to/production/copies/of/modules');
}

use module1;
use module2;
use module3;
#etc

I tested this out and it doesn't seem to be working very well. It looks as though the perl interpreter scans the code for "use" statements and loads whatever modules they request before it executes the rest of the code (e.g. the if statement). So whichever the module used is whichever ends up closer to the front in @INC.

Is there a way to get this to work? Is it possible to have perl execute or not execute "use lib" statements based on conditionals? I'm using perl 5.6.1.
