Hi,<br><br>I am trying to run the Ruby bindings on a Mac OSX 10.6.3. I installed rrdtool 1.3.8 via macports. In addition I downloaded the source for rrdtool-1.3.8, edited the dir_config in bindings/ruby/extconf.rb to:<br>dir_config("rrd","../../src","/opt/local/lib/"), and ran <br>
"ruby extconf.db; make; sudo make install". However when I run my ruby code I still get:<br><i><br>=> Booting Mongrel<br>=> Rails 2.3.7 application starting on <a href="http://0.0.0.0:3000">http://0.0.0.0:3000</a><br>

<br></i>When I run "ruby extconf.rb" I get:<br>checking for rrd_create() in -lrrd... no<br><br>which seems like a bad thing.<br><br>Heres some more info about my machine and rrdtool/ruby binding install procedure. <br>
