No, they have a distribution independent binary installer that also includes private versions of all its dependencies.
In other words, it doesn't matter what versions of QT, python, etc. are installed on the host system as it uses it's own private versions of these. The application as well as all of it's dependencies are downloaded in a tar.gz file that is installed (extracted and setup) under /opt/calibre.
It basically works in much the same way as a windows installer would.
