 ast has variants for choosing which gcc you want. The default today is
 gcc7:

 $ port variants ast
 ast has the variants:

 Perhaps when you originally installed it, gcc5 was the default. But if
 instead of upgrading it you reinstall it without specifying any variants,
 or if you specify the gcc7 variant, it should use that instead of gcc5.
