To be honest, after seeing their head-first jump into gcc4/gfortran, without 
looking if there was any water in the pool at all, I decided to stay behind a 
little.  FC3 continues to be patched (yesterday they FINALLY fixed a 2-year 
old kernel bug which prevented reliable access to USB storage devices), and 
everything builds there.  Making a python2.4-based environment takes a bit of 
extra work, but I'm mostly using 2.3 only so that's fine for me.

It seems to me that gcc4/gfortran are not really ready for production use, if 
you want to spend your time doing work instead of chasing build/compile problems.

In a very selfish way, thank you for going first and getting the arrows on 
your back ;)

Cheers,
