perl587installer.tar.gz completed trashed my perl installation

And this is not the first time, it screwed up my Perl installation on another server as well. In that case i just reinstalled Perl 5.8.4 and left it at that, without being able to successfully upgrade Perl to 5.8.7.

But i just purchased a new RHEL 3 Ent. Server. It came with the standard 5.8.0 installed. A bit old wouldn't you think? I downloaded this perl installater to upgrade. During the upgrade there were errors all thoughout, neither of which i could capture due to the speed of the update.

Now my version of Perl seems to be all screwed up. In the X them Perl Version shows;

PERL version perlversion instead of PERL version 5.8.7

When i click on Perl modules it returns a blank page.

I need to be able to reinstall Perl from scratch but so far have not been able to do it. If the 581 or 580 perl installation was still available at layer1 i would trying downgrading but its not, cpanel has removed it.

If i move /usr/lib/perl5 to perl5_old and try to recompile i get perl module erorrs like conf.pm is missing. I just want it to recreate /usr/lib/per5 with the 5.8.7 libs there.
