Forum: Ruby ruby bindings for RRDtool

Hi

I installed RRDTool on mac & am trying to use RRD from Ruby but it is
not able to find the Ruby bindings? The documentation says that perl,
ruby bindings are included by default

Can anyone pls help, where would I find the ruby bindings ?


Thanks in advance

Pradeep

Check out the path to the libraries in the example: they're installed 
locally in the RRD directory, so hand in the appropriate path on your 
system.
