[Nagiosplug-devel] Integrating Nagios::Plugin into thedistribution

[Patrick Proy]

Hi,

As a plugin dev I think using a specific directory for Perl module will
create the same problem that I had with the config.pm file : the plugin
won't run on all systems without changing the include path in the plugin.

The easy thing about perl standard lib directory is that the plugin doesn't
have to know the system specific directory of the perl modules.
I don't know about possible breakages on distro upgrades, but I think Perl
should be able handle this.

I had quite the same problem with the Net::SNMP library, but setting my own
copy in a specific directory ended up with big problems (especially for
dependancies).

My personal preference is #2, though we may need to rename it slightly to
avoid Perl complaining (AFAIK Perl complains when you have a lib with the
same name in more than one INC path).

The reason of this preference is that we can properly test all Perl plugins
with the released version so that we'll avoid bug reports due to newer/older
N::P libs and also avoid having to ask which version of N::P users have when
they report bugs. IMO this will save us a lot of time in the long run. It is
also simpler for the user to just "make install" (which should install the
lib locally) and get everything in place and will avoid possible breakages
on distro upgrades (i.e. if Perl libdir change).
