Yes, it is a problem, I agree. There are too many dependencies in scipy, 
with too much magic to make some things work. It would be much better to 
cut the dependencies, and support fully a restricted set instead of 
supporting many things at 50 %.

I do not share your optimism :) People will still have trouble with 
atlas, etc...

You would be surprised :)

Looks easier than building gcc with a non glibc is more difficult, though.
