At present I have clang 3.4, 3.7 and 5.0 installed. Don't know why not 3.9 but then, none of these were deliberately installed anyway, all pulled in as dependencies. But I gather from the file you reference below this is not enough. In fact, it seems like to follow that I really should get rid of all the MacPorts stuff and start from scratch. Or is that too extreme?
In my experience when compiling stuff on these older systems (10.5 and 10.6) clang 3.9 is very good... usually it is quite enough, yet works well! gcc 6 is the other "good one". Both are recent enough...
Another question is about software (not in MacPorts) that relies on the gcc compilers (gcc, gfortran). Do I run the risk that I cannot build that anymore? This isn't my own stuff but progs I get from others so I don't control what they need. Will gcc still build? The specific package I am thinking about is a cli program using Xwindows, so macOS GUI stuff is not a concern.
You still keep XCode's compiler, MacPorts gives you added compilers for compiling stuff which can be useful! Why do you worry? MacPorts compiler can also compile MacOS GUI stuff - up to a certain point when the compiler is too new and has issues with older SDK's.
