Suggestion :
I had to install Circos lately and their procedure for the installation is very intuitive, they have a utility that does the check prior to installation and see what kind of dependency is there or not.
It would be great to see that in the installation shell script, rather than "breaking" each time a dependency is not found, why not just carry on, check the next and then report all missing libraries at the same time, it is better than running the installation script each time and figure out we miss a thing
Thanks
