Comment (by jim.king@…):

 Using "strings" I extracted the mangled name from the library:

 {{{
 # strings /usr/lib/libboost_filesystem-clang35-mt-d-1_56.so | grep
 copy_file
 _ZN5boost10filesystem6detail9copy_fileERKNS0_4pathES4_NS0_11copy_option9enum_typeEPNS_6system10error_codeE
 ...
 }}}

 This demangles to:

 {{{
 boost::filesystem::detail::copy_file(boost::filesystem::path const&,
 boost::filesystem::path const&, boost::filesystem::copy_option::enum_type,
 boost::system::error_code*)
 }}}

 The ::enum_type is a different signature.

 I built boost 1.56 with:

 {{{
 ./b2 toolset=clang --prefix=/usr  --build-type=complete --build-dir=...
 --layout=versioned install
 }}}

 (where ... was a directory outside the source directory)
