Yeah, that explains the segfault Chase was seeing. I didn't see the segfault 
on regular system apps, like make, ls etc. But it did segfault on Arago 
toolchain binaries, like arm-arago-linux-gnueabi-gcc etc. It's better to set 
LD_LIBRARY_PATH variable only for select SDK tools that we have shell stubs 
for, instead of globally. The fix is now in.

I guess it's rather host system specific...
