[rrd-users] Trouble installing rrdtools Ruby bindings on Mac

[Sanjit Jhala]

It works after I made the following modifications to extconf.rb:
*
dir_config("rrd","../../src","/opt/local/lib/")
have_library("rrd", "rrd_create", "rrd.h")*

and then ran:
*ARCHFLAGS="-arch x86_64" ruby extconf.rb –with-rrd-dir=/opt/local*
