FORK NOTES
This is a forked version of this gem to play nice with CentOS 6.7 64 bit.
A pull request that may or may not be generally useful has been sent to the owning repo.
I was getting the following error running the IMGKit gem on Centos:
libjpeg.so.8: cannot open shared object file
For this modified branch, it contains the wkhtmltoimage binary specifically for Centos 6 64bit, compiled on Centos 6.6, extracted from the rpm package at http://wkhtmltopdf.org/downloads.html.
Also was hitting error with the lsb_version check so added a thrown error if that command fails so at least it would be easier for someone to fix the issue (ie adding the package containing that command).
