</div></div>so you would want me to maintain packages for each of the scripting<br>
languages supported by rrdtool (which are tied to features in<br>
certain versions of the library) independently of the main program<br>
and keep them updated in the different scripting languages<br>
repositories ?<br></blockquote><div><br></div><div>Nope, not what I'm saying at all, sorry if I was unclear. I was responding to Cosimo's question, "Doesn't that make CPAN distributions that need to depend on RRDs/RRDtool automatically broken?" My point was that RRD::Simple is not "automatically broken" because it's dependent on RRDs/rrdtool, just like XML::LibXML is not broken because it's dependent on libxml2. Some Perl modules have external dependencies; if you want to use those modules, you have to install the dependencies yourself. You can't expect the CPAN shell to install libxml2 for you, and you can't expect it to install rrdtool for you either.<br><br></div><div>The way you're currently packaging RRDs is fine, and I can't imagine it working very well on CPAN because of the version dependencies you mention.<br></div></div></div></div>
