Looking back across this thread, I think almost everyone agrees we  
have to support installing N::P in a nagios dir for simple  
installation (as Matthias points out), and for sites which do not  
allow changes to system perl dirs (as John points out).

The only dissenting opinion is from Gavin, because of duplication of  
N::P (local v system dirs) and making a deployment decision within  
code (by using FindBin).

I'm not sure how to overcome the duplication, though a well managed  
system will have one or the other. If we clearly say a plugin prefers  
a local dir if it is there, that should make it clear which module is  
being used.

The FindBin objection is hard to overcome too. Using PERL5LIB means  
more work for the user, setting up in various places (nagios user's  
profile on all monitored boxes, NRPE and Nagios start up scripts) - I  
can envisage more support calls coming from this decision. I'm not  
entirely convinced that using FindBin is that bad either - I think it  
is equivalent to using LD_RUN_PATH, which some Solaris people use to  
link to openssl (though admittedly, this is a decision they make at  
compile time, not always in the code at execution time). I guess we  
could have an option to strip out the "use lib" lines from the  
plugins at make time - would that be sufficient?

I agree with Thomas that we always install N::P locally, though we  
provide configure switches to turn off.

Is it fair to say we should proceed with the current plan?

BTW, I saw a link to http://search.cpan.org/~adamk/Module- 
Install-0.65/lib/Module/Install/Bundle.pm which looks like it could  
provide the answer to the nanocpan idea - we create a bundle called  
Bundle::Nagios::Plugin which contains all the dependencies.
