Hi Wolfgang
Thanks again. I tried, but I still get an error saying that Cairo cannot generate an executable (or something in that line). I compiled all libraries manually. I contacted our HPC provided and they will set me up with a newer distro of OpenSUSE so I can use this one instead.
Thanks a lot for all the help. I keep you posted if I find any problems or have any comments on the package, which looks great BTW.
Cheers
Paulo

I noted though that older versions are sticking around on the internet. Also note that the "Cairo" R package is not the same as the "cairo graphics library" e.g. at http://www.cairographics.org. You should not need to put anything into /opt or point R to it or anything like that.
