Is the configuration subsystem missing something about my system's setup? Please advise. I'm happy to provide any other details if necessary.

You'll need to apply the following patch for compiling GnuPG (the patch
is made to be applied before ./configure is executed):

<https://sourceforge.net/p/gpgosx/source/ci/master/tree/patches/makefile.patch>

And most likely, you'll run into another build error in dirmgr. This can
be fixed by editing dirmgr/Makefile and deleting "-R/path/to/somewhere"
from LDFLAGS
