In the short term yes. Hopefully though, over the long term it will  
bring much of os x code closer to the x86 linux and bsd code. I have  
made the big vs little edian mistake more than once on os x.

I think you are good to make the change. This worked fine on my  
powerbook. Tues when I'm back in my office, I'll test in on my G5.  
However, I see no reason why it would be any different. Additionally,  
did a small edit on the config file to get the base R program to  
build on os x. If you want I can send you that too.

Thanks again,
