Is it? AFAIK, there are no specific requirements on the library name
itself (by which I mean everything between 'lib' and '.so' or '.a'). It
can be 'boost_filesystem' or 'boost_filesystem_mt' - I don't see much
difference for packaging purpose.

But why introduce the danger of misuse, especially when there is no such
problem now?
