re-build again all the installed packages

[Marco Calviani]

Dear list,
I've just install a new version of Xcode that contains apple-gcc-4.2. Since
now some ports are compiled with gcc-4.0 and some other with gcc-4.2, I
would like to know how (and if) is it possible to recompile all the packages
installed in the system, something like the #emerge -e world command present
in Gentoo linux distribution.

Regards,
Marco
