I do not understand why, but I guess I am aware that "echo" is not 100% portable, so what I have done is probably an improvement in general.

The Makefiles I had for a Mac in the "ordinary" way managed that, but under Macports that would need some extra fuss - the easiest way out was to discard it in the Mac in general.

dyndemo.c includes the following headers: config.h, dlfcn.h and stdio.h.

I searched my mac and found:

It looks to me that my macports installation does not support the dlfcn.h header.
