somthing wrong with perl?

[69cruiser]

I'm trying to install ispCP on Ubuntu 9.10 Karmic and I don't seem to be able to get very far... I have a feeling im missing somthing, this is the output:

/var/www/ispcp/engine/setup# perl ispcp-setup Can't locate DateTime.pm in @INC (@INC contains: /var/www/ispcp/engine/setup/.. /etc/perl /usr/local/lib/perl/5.10.0 /usr/local/share/perl/5.10.0 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl .) at ispcp-setup-methods.pl line 43.
BEGIN failed--compilation aborted at ispcp-setup-methods.pl line 43.
Compilation failed in require at ispcp-setup line 49.

Still getting the hang of things and im not sure what is wrong here, any help would be GREATLY appreciated.

Thanks,
Cory
