I haven't tested other modules yet; I'm still building quad- 
architecture GCC 4.2.4 with AT&T and Apple patches. Got that MacPorted  
yesterday after two weeks' work... now we have a gfortran that plays  
nice with Apple-patched GCC, I think.

Yes, I am hoping to build up our local NRAO/CASA package toolchain  
quad-architecture. I don't know how far I can get. I already have an  
Intel 32/64-bit Qt; that's TrollTech's Cocoa version (expected to  
release as Qt 4.5). I would need to build all of SciPy quad-arch to  
make this fly...
