Upgrade IspCp 1.0.6 to 1.0.7

[LordISP]

I have a similar problem and it's quite confuse and stupid together
I run “perl ./ispcp-update” and get the same message as mentioned:

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-update line 46.

If I check the perl version using “aptitude show libperl-version-perl”, I get:
The packet libperl-version-perl could not be found.
But if I run the install command “aptitude install libperl-version-perl” aptitude does not find a version that could be installed.
I checked my /etc/apt/sources.list file as well :

Code:

deb http://ftp.de.debian.org/debian/ lenny main non-free contrib
deb-src http://ftp.de.debian.org/debian/ lenny main non-free contrib

deb http://security.debian.org/ lenny/updates main contrib non-free
deb-src http://security.debian.org/ lenny/updates main contrib non-free

I’m running Debian GNU/Linux 5.0.8 (lenny)
You help is much appreciated!
