  #48471 https://trac.macports.org/ticket/48471

  #49381 https://trac.macports.org/ticket/49381

both refer to build failures under El Capitan (in my case, OS X 10.11.1) involving gcc48.

I migrated macports from Yosemite to El Capitan per usual steps. Some 72 ports would not reinstall, most if not all due to the gcc48 problem indicated in those tickets.

The issue is not just that gcc48 cannot be used for certain other port builds, but:

   gcc48 itself fails to build.

Following suggestions at #48471, I tried to edit Availability.h. But even using sudo with an admin account, OS X refused to allow me to edit Availability.h.

As a number of the ports involved will not install, with their needed variants, using later versions of gcc, including gcc48, using a different version is not a solution. (gcc 47, gcc49, and gcc5 did reinstall OK.)

What's to be done?
