Comment (by jinmei):

 Please review the proposed change to configure.ac in trac2147.

 Regarding the second issue, on a closer look I guess the difference is
 that the installed user.hpp defines BOOST_NO_CONFIG, which prevents
 compiler-specific config from being included, which would otherwise
 prevent this build failure.  We could avoid this by not including
 the user.hpp by specifying BOOST_NO_USER_CONFIG:

 {{{
 % ./configure <other options> CXXFLAGS=-DBOOST_NO_USER_CONFIG
 }}}

 This is the proposed `ChangeLog` entry:
 {{{
 456.?   [build]*        jinmei
         BIND 10 now relies on Boost offset_ptr, which caused some new
         portability issues.  Such issues are detected at ./configure time.
         If ./configure stops due to this, try the following workaround:
         - If it's about the use of mutable for a reference with clang++,
           upgrade Boost version to 1.44 or higher, or try a different
           compiler (e.g. g++ generally seems to be free from this issue)
         - If it's about the use of "variadic templates", specify
           --without-werror so the warning won't be promoted to an error.
           Specifying BOOST_NO_USER_CONFIG in CXXFLAGS may also work
           (which would be the case if Boost is installed via pkgsrc)
         (Trac #2147, git TBD)
 }}}
