Your solution works, except for stripping newlines (because of the chomp). If you just change the print FILE2 line to:
print FILE2 $Previous, "\n";
Then it will do what you want.

Here's an alternate command-line solution:
perl -ane 'print unless $seen{$F[0]}++' /tmp/data
See perlrun for the -ane options. Here's what it looks like in use:
[me@host me]$ cat /tmp/data COMPUTER DISTRIBUTION_ID STATUS </br> 30F-WKS `1781183799.xxxx1' IC---</br> 30F-WKS `1781183799.xxx11' IC---</br> ADM34A3F9 `1781183799.41455' IC---</br> [me@host me]$ perl -ane 'print unless $seen{$F[0]}++' /tmp/data COMPUTER DISTRIBUTION_ID STATUS </br> 30F-WKS `1781183799.xxxx1' IC---</br> ADM34A3F9 `1781183799.41455' IC---</br>

[Corion]: LanX: Yes, that's the main problem - you have lots (and lots) of workarounds in various places and stages of the processing, and to clean that mess up requires action across the complete codebase. And it's almost impossible to do it piece-by-piece
