I'd think that this happens depending on how your PATH variable is set 
up. I just installed the "gcc-arm-linux-gnueabi" package, and have the 
additional tools like "as" under "/usr/arm-linux-gnueabi/bin". So, if 
you additionally manipulate the
PATH of your ARM construction environment and prepend this folder to it, 
things should work fine.

If not, I wonder what exactly you are doing in your 
"use-arm-tools/use-native-tools" scripts. Are they available anywhere 
for download/cloning?

So far, separate environments are still the way to go for me. And it's 
the more "SCons"ish approach... ;)

Best regards,

Dirk
