@knasim, yeah, that is true. If you do not have sudo rights, you also have to compile the dependencies from source.
At the time of writing this script, I had sudo rights, so I just installed the dependency via yum.

@jdhao
do I need to add this in my profile?

export PATH=/usr/local/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/lib64:$LD_LIBRARY_PATH

or optional?
