Thanks. The main.log shows:

So it looks like I need legacysupport's CFLAGS and LDFLAGS and they're not
getting through. It's odd that I only saw linker errors, and no compiler
warnings without the CFLAGS getting through. Never mind.

I'm currently setting the CFLAGS and LDFLAGS macros myself in the (non-GNU)
Makefile, made up of a list of other *_CFLAGS and *_LDFLAGS macros.

So if I use different macro names (e.g. ALL_CFLAGS and ALL_LDFLAGS), and just
add $(CFLAGS) and $(LDFLAGS) from the environment to it, then it should work.
I'll try that.

Yay! It worked. Many thanks. I'll fix my Makefile for the upcoming version
of rawhide and create the Portfile for that.

cheers,
