Q:
Thank you for offering VAT free to scientific community. A few users of our cluster requested this software to be installed on our 6000 node cluster.
But I ran into problem while trying to compile it. Hopefully you can provide some help.Thank you in advance.

I have followed your instruction on
http://vat.gersteinlab.org/documentation.php
But when I try to make vat, I got following errors. I have attached the
config.log file.:

A:
Thank you for your interest in VAT. It appears that the compiler is unable to find the reference for gdImagePng, which is part of the GD library.
It is important to install and configure the GD library before installing VAT.
