It took longer on my P4 3.6GHz:

The tree (15689ports) takes  2789.84287214 seconds to explore.
Now computing the recursively extended dependencies.
Took  3.02815794945 seconds.
Now converting to packages and sorting.
Last phase takes  4.7659368515 seconds.
Total time spent:  2800.94901609 seconds.
python build_index.py  3024,42s user 2050,37s system 181% cpu 46:41,64 total

Remarks:
- this is not a benchmark, and I was using the machine in the same time;
- I have several local ports or local tweaks which have been reported as
"The port             xxx/yyy is obsolete".
