I have only read the GNU make manual up to section 4.5, but I think I have
read enough of the manual to realize that the tab character is required
between all commands. So I have fixed that, but have received the following
error the first time through:

I have inferred that the linker path LNK is in the wrong directory. So I
changed to LNK = $(TOOLSDIR)/share/gputils/lkr/ for the microcontroller
linker path b/c the linker file is found in that respective path, but
instead got a permission error message.

Does anyone have any idea on how to get around that? I have a feeling that
it has something to do with 18f2620.lkr file.
Thanks,
Stanley
