Comment (by kencu):

 I have the fixed openblas, so no dupicate RPATH errors, but it still won't
 build (MacOS 14.2.1 arm64):

 first error I see is:

 {{{
 Traceback (most recent call last):

 line 100, in process_pyx
     r = subprocess.call(['cython'] + flags + ["-o", tofile, fromfile],

     raise child_exception_type(errno_num, err_msg, err_filename)
 FileNotFoundError: [Errno 2] No such file or directory: 'cython'
 }}}

 so I did this simple fix:
 {{{
 % sudo port select cython cython39
 }}}

 and then after that, the next error is:

 {{{
