Dear Monks,

I am trying to figure out how I got caught by a strange module install issue and how to prevent it in the future. About a year ago I installed module Test::SDK (which doesn't seem to be around any more). 

       Tue Nov 27 11:31:59 2001: "Module" Test
       ·   "installed into: /usr/lib/perl5/5.6.1"
       ·   "LINKTYPE: dynamic"
       ·   "VERSION: 1.18"
       ·   "EXE_FILES: "

       Tue Nov 27 11:32:07 2001: "Module" Test::SDK
       ·   "installed into: /usr/lib/perl5/5.6.1"
       ·   "LINKTYPE: dynamic"
       ·   "VERSION: 0.04"
       ·   "EXE_FILES: "

The Test::SDK bundle included Test-Simple-0.19. Today, I tried to upgrade to Test-Simple-0.47. 

      Thu Dec  5 13:17:35 2002: "Module" Test::Simple
       ·   "installed into: /usr/lib/perl5/site_perl/5.6.1"
       ·   "LINKTYPE: dynamic"
       ·   "VERSION: 0.47"
       ·   "EXE_FILES: "

This install went to /usr/lib/perl5/site_perl/5.6.1, instead of to /usr/lib/perl5/5.6.1. Since the latter is earlier on my @INC path, the upgrade didn't work until I deleted the earlier modules.

My question is, what can I do to prevent being caught when CPAN moves modules around like this? I have a little script I used to find the problem once I realized it, which might be a starting point. 

use strict;

if ($#ARGV < 0) {
   die "Usage: which.pl fname\n";
}

my $fname = $ARGV[0];

my $dir;
foreach $dir (@INC) {
   print "Checking $dir\n";
   if (-e "$dir/$fname") {
      print "Found $dir/$fname\n";
   }
}
