Here is some working code.

Pretty printing is left as an exercise: 

#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;

my %lic_info;
my $pending_product="";
my $pending_user_count=0;

my %actions=(
   "Flexible License Manager" => sub{ 
         @lic_info{qw|DAY DATE TIME|} = $_[0]=~/ on (\w+) (\S+) (\S+)$
+/;
       },
    "Users of " => sub{
        my ($product,$issued, $usecount) = $_[0]=~/Users of (\w+):  \(
+Total of (\d+) license\w? issued;  Total of (\d+) lic/;
        $lic_info{$product}{ISSUED}= $issued;
        $pending_user_count = $lic_info{$product}{USED}= $usecount;
        $pending_product    = $product;
    },
);

my $regex = "(" . join ("|", keys %actions) . ")";


while (<DATA>){
   if ( m/$regex/ ){
      $actions{$1}->($_); # Where the work happens 
   }elsif ($pending_product){
      next if m/^\s+$/;
      next if m/floating license/;
      next if m/\s*\S?$pending_product/;
      push @{$lic_info{$pending_product}{USERS}},
         m/(\S+)/;
      --$pending_user_count or $pending_product = "";
   }
}

print Dumper \%lic_info;

Update: FYI/FWIW - I was a ClearCase admin in a previous job, decades ago, and I sympathize. That was what taught me perl - so good luck !

                As a computer, I find your faith in technology amusing.
