This should probably just use "cp".

Agreed; will do.

It appears to be a BSD function. It's present in GNU libc, but I'm
guessing that other systems might need -lbsd/-lcompat/-lbsd-compat. 
I'll change it to use putenv(), which is a POSIX function.

Huh?

Did the Tcl/Tk configure checks pass?

I'll take a look.

This occurs if HAVE_ZLIB_H is undefined.

Does /usr/freeware/include contain a file called config.h? That would
break stuff.

The CFLAGS definition in the generated make.rules file is wrong:

CFLAGS      =  $(COMPILE_FLAGS) -I$(INCLUDE_DIR) $(EXTRA_CFLAGS) $(USE_TERMIO)

For gcc, the "-I$(INCLUDE_DIR)" should come first.

PNGLIB should include -lm and/or -lz if either of these have to be
specified explicitly.
