Package libnet-perl is a virtual package

[Philipp]

I just tried to install IspCP on a new server, but getting this error while installating the needed Debian packages:

Code:

# apt-get install `cat ./debian-packages-etch`
Reading package lists... Done
Building dependency tree... Done
bash is already the newest version.
bzip2 is already the newest version.
diff is already the newest version.
gzip is already the newest version.
iptables is already the newest version.
Package libnet-perl is a virtual package provided by:
  perl-modules 5.8.8-7etch1
You should explicitly select one to install.
E: Package libnet-perl has no installation candidate

Any ideas? I installed IspCP in the past on 3 different servers and never had this problem before.
