There are multiple factors in play, some per package ./configure scripts
add -I/usr/local/include so that headers are picked up from there by
default,
if compiler alone doesn't have that in it's default search path already.
There are -L/usr/local/lib added by some, and /usr/local/lib in
/etc/ld.so.conf

What I'm really trying to say is that you can't install boost safely
into /usr/local/lib and include, but you should put it in it's own
directory outside of
compilers or ld.so's scope, like for example, /home/username/boost, and
then when you want something to use it, point the package to search it
from there
using package specific configure flags and environment variables like
LD_LIBRARY_PATH, PKG_CONFIG_PATH, and so forth

Bottom line is, It's not a bug you can file to Gentoo's bugzilla, it is
expected behavior
