Thank you, Rob, I almost missed the one issue that got fixed: I no longer get:
./curlopt-constants.c:19:58: error: non-void function 'constant' shoul +d return a value [-Wreturn-type] if (strEQ(name, "DID_MEMORY_FUNC_TYPEDEFS")) return CURL_D +ID_MEMORY_FUNC_TYPEDEFS;
I applied this patch to Makefile.PL:

That got me past an error free make and make install, yay! (Oddly, implementing the patch by hand did not work, but I wanted to learn how to automatically apply them, so I researched that.) When I patched the code with:
patch -b < WWW-Curl-4.17-RT117793.patch
... I was able to successfully make install the code.

I *am* still getting 4 warnings during my make (make test), I am not sure if those are of concern or not:

(note: I reversed your earlier recommendation for the Curl.xs change, and am still able to compile without the CURL_DID_MEMORY_FUNC_TYPEDEFS error.)

Unfortunately as you can see, an old glitch in Makefile.PL seems to have come back to haunt me... I am getting a linking error in the make install that the Curl.o object file was built for a newer OS (10.12, the server OS) than being linked (10.4, which I guess is the lowest common denominator selected, or it could be due to my perl version, see below).

I believe this results from when I tripped over the error: unterminated conditional directive during my initial perl Makerfile.PL call:
/usr/include/AvailabilityInternal.h:22938:10: error: unterminated cond +itional directive #if __MAC_OS_X_VERSION_MIN_REQUIRED >= __MAC_10_12 ^ /usr/include/AvailabilityInternal.h:22867:10: error: unterminated cond +itional directive #if __MAC_OS_X_VERSION_MIN_REQUIRED >= __MAC_10_11_4 ^ /usr/include/AvailabilityInternal.h:22800:10: error: unterminated cond +itional directive #if __MAC_OS_X_VERSION_MIN_REQUIRED >= __MAC_10_11_3 ^
I guess I cannot ignore those error after all. From what I researched, the preprocessor is tripping over indented conditional if/ifndef/etc directives, likely due to its duties testing off-side languages like Python. I hear that using gcc instead can fix the problem, but I have no idea how to encourage Perl Makefile.PL to use gcc instead (which I do have installed).

I thought I might experiment by removing all the leading whitespace on each line of /usr/include/AvailabilityInternal.h , but boy, the OS will NOT let me change that file in any way. Not even via su or sudo.

Even the binary that I did manage to make install has problems running:

These exciting new errors definitely show progress... I am thinking it might be related to ancient 10.4 code running on 10.12. I am thinking I need to fix those OS X version tests in Makefile.PL.

I was able to eliminate the 2nd error (Undefined subroutine &WWW::Curl::_global_cleanup) simply by deleting the reference in Curl.pm, as I read it was not needed, but still cannot eliminate (or even find reference to) Can't find 'boot_WWW__Curl' symbol in /usr/lib/libCurl.dylib

FYI, I located the new code path, and forced it via the use lib directive above. The make install did not include it in per @inc (I should probably install it elsewhere, but where...? There seem to be multiple choices, will the real @INC please stand up):

This leads me to conclude that even though I did a make install, the module is not accessible perl. I only know how to do install modules via cpan (which failed, forcing me into this manual install). Am I missing something fundamental here?

This is one deep rabbit hole.
