Comment:

 I reproduced this error.  I'll fix this problem in PortGoup ruby.

 note:

 - ruby30 or later has "compiler.blacklist { clang < 901 }"
 - ruby try to compile a C-extension with compiler that used compiling
 "ruby" itself
 - if the compiler does not exist on users' environment, this error occurs.
