Failed to install node_xslt on node.js

Question

I am trying to install node_xslt from the command line using

npm install node_xslt

But I get the following error: http://i.stack.imgur.com/ItxFT.png

There are several prerequisites for installing node_xslt:

libxml2 
libxslt 
libexslt 
xml2-config (Needs to be on PATH)

Also, when I tried to install libxml2 and other libraries, I got this error: http://i.stack.imgur.com/sxMg0.png

I am not sure where the xml2-config file is located. It says it should be in my way.
