I see 2 issues with the proposed spec.

1) It would install into %{_libdir}, and so potentially conflict with
redhat's rpms.  I recommend using a different directory.  We
have /etc/ld.so.conf.d, so this is easy to implement.

2) Unless you fix #1, ldconfig would put libboost_signals.so as a link to
redhat's version (because of libboost_signals.so.2).
