libshell-perl : Depends: perl but it is not going to be installed

[oxy]

yeah! I'm not the only one. Perl comes with the ubu 12.04
system installation. If it is a system problem, there should
be loads of people complaining here ... :-/

sudo apt-get install -f

will also bring nothing related to perl.
Problem keeps unsolved!
