Re: Install parallel Perl on Debian

Hi,
To install a perl from scratch on a debian box is realy a Bad Thing© to do.

Debian relays heavily on Perl for a lot of administrative tasks such as installing and configuring packets. Changing the perl version that the systems expects could (and almost certanly will) lead to disaster.

If you realy need perl 5.8.1, then you should either upgrade to testing (sarge) or change your Linux distibution. IMHO, the former solution is the best one.

Yet another possibility, is to dowload sarge's perl packages from debian home site and install them using dpkg. Doing so it's likely to start a cascade of required packages to install, which will fall very short of upgrading to sarge. I strongly advise you against upgrading just perl: upgrade your Debian box to sarge and let it be!

Hoping that this helped
