Node.JS + CentOS + node-waf

I have installed Node.JS on CentOS from source like this: ``` yum install gcc-c++ make git cd /usr/local/src/ git clone git://github.com/joyent/node.git cd node ./configure make make install ``` yet while installing modules via npm I get error: ``` sh: node-waf: command not found npm ERR! threads_a_gogo@0.1.5 install: `node-waf configure install` npm ERR! `sh "-c" "node-waf configure install"` failed with 127 npm ERR! npm ERR! Failed at the threads_a_gogo@0.1.5 install script. npm ERR! This is most likely a problem with the threads_a_gogo package, npm ERR! not with npm itself. npm ERR! Tell the author that this fails on your system: npm ERR! node-waf configure install npm ERR! You can get their info via: npm ERR! npm owner ls threads_a_gogo npm ERR! There is likely additional logging output above. ``` is this issue CentOS related, or what is possibly going wrong? This link suggests that this error should only happen if Node is not installed from source....which in this case it is.
