Comment (by manulcaux):

 Hi,

 The problem is I need gcc5 for another port (gildas). I also need g95 but
 both crash at install. I then uninstall all my ports (sudo port uninstall
 all) to start from a fresh and clean Mac Port install, but both gcc5 and
 g95 are still crashing at install.

 I attach both main.log files.

 Many thanks for helping me.
