No, it is the implementation of the sorting. I didn't have the time to
look into it in detail, but I observed the same problems on my machine
and it seems that there is some O(exp(N)) code (well perhaps not as
bad, but the time is growing too fast).
The actual sorting might be implemented using tsort, then the
remaining code would just have to check that all required modules are
available in the correct version.
