Comment (by ballapete):

 I am already following Ken, subscribed to clamav-announce and found that
 these two lines would fit into `Portfile`:

 {{{
 compiler.cxx_standard   2014
 configure.cxxflags-append   -std=c++14
 }}}

 `configure` seems to check for modern compilers. `Clang` certainly has
 this standard. And with these two lines `port` will certainly
 automatically select `GCC7` on old systems. (`GCC 4.2` cannot compile.)

 To introduce `clamav-legacy` (Tiger…Lion, Mac OS X 10.4…10.7, os.major
 8…11) it's probably best to open a new case, right? `clamav`s "old system
 support" (`if { ${os.platform} eq "darwin" && ${os.major} < 11 }`) does
 not include `Lion` – should I adjust that?
