Package dependencies are not versioned; as the current version of
libboost-devel is 1.57.0, which depends on libboost*1.57, those
dependencies will be chosen regardless of which version of
libboost-devel you choose to install.

Please note that, as the previous version, 1.55 remains in the distro
only for the benefit of packages which have yet to be rebuilt for 1.57.
Once that has been done (and it mostly is already), then 1.55 will be
subject to removal from the distribution.  You would therefore be better
off working with the currently-supported 1.57.0.
