too many prerequisites

I dont know if this work because it’s a nightmare to run at first time. At last it’s impossible to me to install readonly.pm. Too much effort.

The prerequisite Nagios::Plugin doesnt install:
CPAN.pm: Going to build M/MS/MSTROUT/Nagios-Plugin-0.990001.tar.gz

This is a tombstone release, not an installable distribution
Warning: No success on command[/usr/bin/perl Makefile.PL INSTALLDIRS=site]
Warning (usually harmless): ‘YAML’ not installed, will not store persistent state
MSTROUT/Nagios-Plugin-0.990001.tar.gz
/usr/bin/perl Makefile.PL INSTALLDIRS=site — NOT OK
Running make test
Make had some problems, won’t test
Running make install
Make had some problems, won’t install

A little dificult to me. 🙁
