Comment (by easye):

 Replying to [comment:4 chrstphrchvz]:
 > `strverscmp()` is originally a Linux syscall; where do ports normally
 get it from? One way might be to get it from libiberty in GCC, but
 historically this port was able to build with clang. (For some time
 FreeBSD has forced clisp to build with GCC rather than clang.)

 I have just gotten a note from the maintainer of clisp who pointed out
 there is a newer version of clisp available.  I am in the process of
 bringing that version of the Port into MacPorts to see if it makes things
 work under XCode 12.  The newer version of clisp is compiling with XCode
 11.7 for me locally: hopefully the CI builds can show us what happens
 under XCode 12 when I open a merge request.
