Comment:

 Your output shows that rev-upgrade determined that libgcc was broken, and
 then failed to rebuild it. According to the log, the first reasons the
 build failed are:

 {{{
 :info:build
 /macports/var/macports/build/_macports_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_gcc48/libgcc/work/build/x86_64
 -apple-darwin11/libstdc++-v3/include/bits/stl_algobase.h:1000:27: error:

 :info:build    __lg(unsigned long long __n)
 :info:build                            ^
 :info:build

 :info:build                               ^
 }}}

 It might be interesting to know why rev-upgrade thinks libgcc is broken.
 Is it shown in the output of "`port outdated`"? What does "`sudo port -v
 rev-upgrade`" show?
