Problem installing

[Servera]

Code:

root@servera:/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/5.10.1 /usr/local/share/perl/5.10.1 /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.

I'm using Debian 6.

Nevermind.
I reinstalled IspCP and it's working now
