Thanks for your help and critique, I've taken your advice on board:

src/Makefile.am

nuchimp_SOURCES = \
        callback.c callback.h \
        main.c main.h

removed
these 2 lines were in a sample I found

top level Makefile.am
<code>
## Process this file with automake to produce Makefile.in

SUBDIRS = src
</code>

I now get a make error:
*** missing separator: stop
pointing to the 2nd line of:

dist-bzip2: distdir
  tardir=$(distdir) && $(am__tar) | bzip2 -9 -c > $(distdir).tar.bz2
  $(am__remove_distdir)

I removed several paragraphs that defined install/uninstall after
getting this error but it remains.
