Actually, I dont believe there currently is a link dependency to boost.

ldd src/core/libOpenColorIO.so :

linux-vdso.so.1 => (0x00007fff63afb000)
libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x00007f4b3241a000)
libm.so.6 => /lib64/libm.so.6 (0x00007f4b32196000)
libgcc_s.so.1 => /usr/lib64/libgcc_s.so.1 (0x00007f4b31f80000)
libc.so.6 => /lib64/libc.so.6 (0x00007f4b31c30000)
/lib64/ld-linux-x86-64.so.2 (0x00007f4b329e5000)

And, a bit surprisingly, even the unit test program doesnt appear to
link to boost:
ldd src/core/ocio_core_tests:

linux-vdso.so.1 => (0x00007fff09fb8000)
libOpenColorIO.so => libOpenColorIO.so (0x00007f41d812d000)
libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x00007f41d7e1f000)
libm.so.6 => /lib64/libm.so.6 (0x00007f41d7b9c000)
libgcc_s.so.1 => /usr/lib64/libgcc_s.so.1 (0x00007f41d7986000)
libc.so.6 => /lib64/libc.so.6 (0x00007f41d7636000)
/lib64/ld-linux-x86-64.so.2 (0x00007f41d83b3000)


So the only benefit would be to remove it as a compile time dependency
(presuming that we dont let anyone use at link time, either).
