Problem compiling 2.6.6 on Mac running Mojave

Hi folks,

I'm trying to get a more recent version of Dar for my Mac.  I followed the
link from the documentation page:

    Binary Packages for Mac OS
    Binary packages for Mac OS can be fetched from softpedia.
    https://mac.softpedia.com/get/Developer-Tools/Disk-ARchive.shtml

But found that it gave me a source package, not a binary package.  If you
know of any place where I can get a binary package, I'd sure appreciate a
pointer.

I tried compiling on the Mac using:
    ./configure  --prefix=/usr
    make

but received compiler errors (I'll append the errors in case you know
of something
that I did wrong by the error listing.)

            Thanks,
            Jon
