As of Boost 1.32.0, the shared libraries are properly versioned (e.g.
they have a proper SONAME attribute set and there is a
libboost_XXX.so.1.32.0). Is this change necessary then?
There is the unfortunate matter of the version number being encoded in
the name TWICE now (e.g. libboost_thread-gcc-mt-1_32.so.1.32.0) which
I think is a problem and should be corrected. The versioned shared
object should be sufficient without having to encode the Boost version
in the part of the name that comes *before* .so.
