Thanks!!! with the new MooseX it works!

Now follows the rest of my email that I wrote before reading your PS.

This is perl, v5.8.8 built for i686-linux-thread-multi

When I was saying Moose array I was meaning the ArrayRef constraint
isa => ArrayRef
I have no experience with Moose, but I was assuming that or Moose
bless the array to be able to call methods, or there is an operator
overloading changing the meaning of the '->'. But anyway, I just
started with Moose and still don't know how it operates its magic.

This is the thing that puzzled me. Probably I have installed an unused
dependency in the past with force  and now is hitting me back.

I will leave this as it is at the moment. Probably this would be a
problem with my configuration [I don't have root access at work] and
this was an install in my home dir to play with catalyst in order to
have something before asking my system administrator to install the
whole thing in the development server. I managed to install it in my
macbook so I can use it with the new catalyst book :-).

I leave this here for the internet archive, I would come back when I
have a better understanding how to debug and follow Moose magic to
narrow down the place of the error. But I am sure that if I create a
new PER5LIB only for catalyst and install all from scratch it will
work. I would try to find the time some day ;-)
