Cannot find perl.h when installing Tk on macOS Catalina 10.15.5 #66

I am trying to install Tk using the system perl (version 5.18.4) on macOS Catalina 10.15.5:

$ perl Makefile.PL
Cannot find '/System/Library/Perl/5.18/darwin-thread-multi-2level/CORE/perl.h' have you installed perl?
Compilation failed in require at Makefile.PL line 37.
BEGIN failed--compilation aborted at Makefile.PL line 39.

I believe this is because Apple removed the Perl system headers from archlibexp in macOS 10.14, see this issue for more information. I get the following:

$ perl -MConfig -E'say $Config{archlibexp}'
/System/Library/Perl/5.18/darwin-thread-multi-2level 
$ ls /System/Library/Perl/5.18/darwin-thread-multi-2level/CORE
libperl.dylib

So there is no perl.h there, but on the other hand Apple has moved the header to this place:

can this be solved in any way? how would I tell the installer to look in the right place for the header-file?
