This is much better!  :-)

Also interesting would be:
  objdump -p .libs/lt-clic
and
  objdump -p /path/to/.libs/libmnnbase.so

(you can pipe the output through
  egrep 'PATH|NEEDED'
if it's too long for your taste).

This is part of clic_LDADD or LIBS, right?

This is part of libnmmbase_la_LDADD, right?

Is libnmmbase a library that will be installed (i.e., is it listed in
something like lib_LTLIBRARIES or noinst_LTLIBRARIES)?  What about
libnmmutils?

For both of these, I'd very much like to see what libtool makes out of
these -- post the output of those commands.  To avoid having to ask you
again, please add --debug as first libtool option.  Pack the output
(gzip or preferably bzip2) and attach, like so:
  /bin/sh ../../libtool --debug --mode=link ..... >linklog 2>&1
  bzip2 linklog
  (attach linklog.bz2)

It's enough to make me suspect a genuine libtool bug, but not enough to
be able to locate or reproduce it.  Actually, I can build most of the
package just fine.

But I should be able to provide you with a workaround:  add
  $(top_builddir)/nmm/utils/libnmmutils.la
(and if necessary also libnmmnetutils.la) to clic_LDADD.
Please report whether that works.

Please also tell me where I can direct bug reports against nmm (mailing
list?) and whether patches should be sent against version 0.7.0.

Thanks,
Ralf
