Not true. You can have multiple versions of a perl module in @INC,  
but the first one will be used (like PATH). If you 'use lib "/path/to/ 
mods"', this is put at the front of @INC.

I think tweaking the name would cause more problems.

Agreed that there is an additional question to ask at support time.  
You can specify a minimum version of a module via perl ("use  
Nagios::Plugin 0.15;"), which should help with older versions (but  
won't help with newer versions that break compatibility - hopefully  
not very often).

Consider the C case - we may check for a minimum version of a library  
and complain if it is too low - I'd guess we'd do something similar  
with N::P at configure as well as runtime.
