Builde nodejs and ZMQ on a shared host when build tools are available

Build node.js and ZMQ - step 1.sh

# 1. Downdload the latest distribution from http://nodejs.org
# 2. Extract the nodejs distribution
$> tar zxvf node-{version}.tar.gz
$> cd node-{version}

# 3. Configure and gmake with the location for your distribution i.e.
$> ./configure --prefix=$HOME/local
$> gmake
$> gmake install

# 4. Make sure that the PATH variable includes local/bin in your 
#    if not so update your  .bashrc / .bashrc_login or .profile file to include it
PATH=$PATH:$HOME/local/bin; export PATH

# 5.The node binary should be available from local/bin now
$> which node

# 6. Make sure to set the NODE_PATH in your .bashrc / .bashrc_login or .profile file
NODE_PATH=$HOME/local/lib/node:$HOME/local/lib/node_modules; export NODE_PATH

Build node.js and ZMQ - step 2.sh

# 1. Download the latest zmq library from http://www.zeromq.org
# 2. Extract the zmq distribution
$> tar zxvf zmq-{version}.tar.gz
$> cd zmq-{version}

# 3. Configure and gmake with the location for your distribution i.e.
$> ./configure --prefix=$HOME/local
$> gmake
$> gmake install

# 4. Make sure to install the required node-gyp library
$> npm install -g node-gyp  
 
# 5. Download or clone the latest zeromq.node from https://github.com/JustinTulloss/zeromq.node
$> git clone https://github.com/JustinTulloss/zeromq.node.git
$> cd zeromq.node

# 6. Change the bindings.gyp file to include the correct path to search for when building
# Replace $HOME with the actual location just in case
$> vim bindings.gyp
