I recently pushed rb_libtorrent 0.12.1 to Rawhide. This changes the soname (thus
requiring a rebuild) but also modifies a bit of the included asio error checking
code, so the attached patch adapts linkage 0.1.4 to properly use this for error
checking in its SessionManager code.
This seems to fix the build error (minus the GCC 4.3 error which may be a
missing #include <cstdlib>), though I have not tested it at runtime.

Build fix w/ rb_libtorrent-0.12.1 (updated asio error handling in the SessionManager code)
Thanks for the patch, should be fixed in linkage-0.1.4-6.
