I agree that this will allow /usr/local/bin/guile to load 
/usr/local/lib/libguile*.

However, won't it also cause /usr/bin/guile (2.0.5) to load 
/usr/local/lib/libguile* (2.0.11) ?  If not, what is the mechanism that 
tells /usr/bin/guile (2.0.5) to load /usr/lib/libguile* (2.0.5) instead 
of /usr/local/lib/libguile* (2.0.11) ?

Thanks,
