Comment (by chrstphrchvz):

 I guess it's time to reopen this already. The port is deciding whether or
 not to build its bundled copy of the GMP library based on whether it
 detects system GMP, which is almost certainly a problem. I have **only**
 Xcode 12 beta 5 CLT, and only get the `no appropiate integer type for the
 cl_fixnum type` error if I allow `ecl` to find MacPorts' `gmp`; whereas
 under trace mode the bundled GMP fails to configure:
 {{{

 }}}

 I would be inclined to see if MacPorts' `gmp` can be used, since its
 portfile has quite a bit of effort put into it. The bundled GMP appears to
 be very old (4.2.1, from 2006), but Debian for example is able to build it
 with GMP 6.2.0.
