 Right, we knew from the main.log that this was the problem, but we needed
 the config.log to see why this was the problem. And the config.log tells
 us this test is failing because:

 {{{
 conftest.c:15:1: error: use of undeclared identifier 'FILE'
 FILE *f = fopen ("conftest.out", "w");
 ^
 }}}
 {{{
 conftest.c:15:11: warning: implicit declaration of function 'fopen' is
 invalid in C99 [-Wimplicit-function-declaration]
 FILE *f = fopen ("conftest.out", "w");
           ^
 conftest.c:15:11: warning: declaration of built-in function 'fopen'
 requires inclusion of the header <stdio.h> [-Wbuiltin-requires-header]
 }}}
 {{{
 conftest.c:16:9: warning: implicit declaration of function 'ferror' is
 invalid in C99 [-Wimplicit-function-declaration]
  return ferror (f) || fclose (f) != 0;
         ^
 }}}
 {{{
 conftest.c:16:23: warning: implicit declaration of function 'fclose' is
 invalid in C99 [-Wimplicit-function-declaration]
  return ferror (f) || fclose (f) != 0;
                       ^
 }}}

 These are some pretty basic things to be failing. `FILE` is the standard
 variable type for dealing with files. `fopen`, `ferror`, `fclose` are
 standard functions for dealing with files. If they're not there, something
 is wrong with your compiler setup (such as the standard headers are
 corrupted or aren't there at all).

 The warning that <stdio.h> must be included seems promising at first, but
 if we look at the code in the configure script we see that it is already
 being included:

 {{{
 #include <stdio.h>
 int
 main (void)
 {
 FILE *f = fopen ("conftest.out", "w");
  return ferror (f) || fclose (f) != 0;

   ;
   return 0;
 }
 }}}

 So we must look elsewhere for the culprit.

 I see this at the top of your main.log:

 {{{
 version:1
 :debug:main Starting logging for cpuminer @2.5.1_0
 :debug:sysinfo macOS 10.14.6 (darwin/18.7.0) arch i386

 :error:main Port cpuminer requires a full Xcode installation, which was

 }}}

 This tells us you initially tried to install cpuminer while running
 MacPorts 2.7.1 and it failed saying this port requires Xcode to be
 installed. That's not actually true, but I think MacPorts base might
 erroneously say that if the command line tools aren't installed or aren't
 working properly.

 You then upgraded to MacPorts 2.8.1 and retried the installation. MacPorts
 2.8 now prints the command line tools version in the log and it claims you
 have CLT 10.3 installed but that information just comes from the
 installation receipt. It's possible for the command line tools to have
 been damaged or removed without the receipt having been affected.

 I'd try reinstalling the command line tools. 10.3 is a perfectly
 reasonable version to use on macOS 10.14; you can get the installer here:
