 Ok. Sounds like it's not #59786 then but rather that this configuration
 script is somehow incompatible with clang 9. Would be good if there were
 some way to see what error is being generated.

 flags being passed to the default compiler that is used, gcc-4.2, that it
 doesn't understand:

 My assumption is that when you ran the configuration process above without
 specifying CC and CXX it defaulted to using g++-4.2.

 this Makefile looks like it has the right compiler in it:

 I'm not totally familiar with how perl stuff builds but we've certainly
 run into situations before where it builds using the compiler perl was
 built with. It seems reasonable to think that the above would make it
 build with clang 9. But evidently not.

 You could grep for /usr/bin/g++-4.2 in the p5-wx work directory (after
 you've run the configuration) and/or in the files installed by your perl
 ports and modules and see if you see anything relevant.
