Yep. That is the exact set of programs which use FFTW. Can you provide
the actual error messages?

That's to be expected; it's called "PNG", not "png", e.g.

AFAIK, the binary should work with both 5.0.x and 5.3.

I'm not sure that there are any direct benefits.
I was under the impression (although I could be wrong) that the idea
was ultimately to remove the copy of PROJ which is currently included
in the GRASS source tree in favour of an external PROJ library once
any issues had been resolved, and the option of using either the
bundled version or an external version was a transitional measure.

I believe that you need a fairly recent version of PROJ.
The actual error messages from config.log may be of use to someone.
