Install Ghostscript v 9.05 (or newer) on CentOS

It turned out that you can easily download a binary from the repository, unpack it on the file-system and then just update the PATH variable. After that the application works fine.

In case anyone else comes across this:

I found this link more helpful. It lists different versions, and then you can download a convenient *.tar.gz to unpack / install.

I did wget on the URL for the link ghostscript-9.10.tar.gz. For some reason it saved to a file called download, but it is a .tar.gz. So I unpacked with tar -zxvf download

cd into the new directory, then it's the classic:

./configure note that you can add --prefix=path to specifiy the installation directory

make

make install

This link from ghostscript's site was very helpful to me for installation
