Off topic: it is perfectly fine to install things like PyQt / PySide on a headless server. I suppose the problem is because the distro doesn't provide these packages? Also, PhantomJS works fine in this case because the binary in the tarball is statically compiled. You can find a whole lot of qt stuffs inside PhantomJS source repository. There ain't no such thing as "truly headless".
