Comment (by NicosPavlov):

 You can refer to [https://trac.macports.org/wiki/howto/InstallingOlderPort
 how to install older ports] for detailed instructions.

 > I did the following:
 > 1. `port uninstall gcc-level libgcc-devel`
 > 2. changed Portfile
 > 3. `sudo port install`
   This command `sudo port install` (if that is exactly what you ran) does
 not work. You need to specify which ports to install, i.e. `sudo port
 install gcc-devel libgcc-devel`. You can also check which ports are
 installed with `port installed`.
