I did not mean to imply that it was building with some other toolset but 
that it is executing some other executables mentioned in my 
user-config.jam, for what reason I do not understand. I posted the 
result of:

b2 --debug-configuration toolset=gcc-4.8.1

on the Boost Build forum after asked to do so but never heard anything 
further. The output shows that clang is being executed for some reason 
or other.
