It appears that no recursion is happening passed the initial dive. {
ProcFiles("/tmp") }
Check my comments.

<Snip && Replace>
#!/bin/perl -w
use strict;

sub ProcFiles {
    my $dir = shift;

    opendir( DIR, $dir ) or die $!;

    while ( my $file = readdir(DIR) ) {

        next if ( -d "$dir/$file" && $file =~ /^\./ );

        # above makes sure this block of code never gets executed
        if ( -d "$dir/$file" ) {

            printf( "Diving into\"%s/%s\".\n", $dir, $file );

            &ProcFiles("$dir/$file");

            next;

        }

        # your printing files that don't begin with "."
        printf( "Adding\"%s/%s\".\n", $dir, $file );

    }

    closedir(DIR);

}

&ProcFiles("/tmp");
