Migrating an RoR app from Ubuntu Feisty to CentOS 5.2 Part 3: Installing RRD

Continued from Part 2:
I've installed RRD before. I followed these instructions, and took the following additional steps to install development headers for pango and libxml2 (missing from default install of centos)

sudo yum install libxml2-devel

sudo yum install pango-devel

In the instructions above, I downloaded rrdtool source. Next I build and install rrdtool
(1) ran make in rrdtool dir
(2) sudo make install to install in /usr/local/rrdtool-1-3.6
(3) modify the path in /etc/profile to include /usr/local/rrdtool-1-3.6/bin
