I am trying to upgrade to gcc48 @4.8.2 but it fails.

Attaching the log file.

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: 'signed' and 'unsigned' specified together for '__n'

:info:build    __lg(unsigned long long __n)
: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 Is it shown in the output of "port outdated"?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?

Thanks for your help. I did a clean all, and then did a "port upgrade outdated". I was successfully able to upgrade all my outdated ports (including libgcc and gcc48 @4.8.2 ).

This defect can be closed.

PS: Once again thanks for all your help ryandesign and others.
