Compiling gnuplot 4.6.4 on CentOS 5

I compiled gnuplot 4.6.4 on CentOS 5.4

Step 1: Install prerequisites, 
(a) wxGTK and wxGTK-devel,
(b) readline, readline-devel
(c) gd, gd-devel

# yum install wxGTK wxGTK-devel readline readline-devel gd gd-devel

Step 2: Compile gnuplot-4.6.4

# tar -zxvf  gnuplot-4.6.4
# cd gnuplot-4.6.4
# ./configure --prefix=/usr/local/gnuplot-4.6.4
# make
# make install
