Comment (by gnw3):

 My libnetpbm build log only shows a few pages being processed:

 {{{

 Building netpbm converts  many more documents.  In {{{pgmmorphconv.html}}}
 there is:


 {{{
 <p>For more information about morphological convolutions, see e.g.
 <ul>
 <li><a
 href="http://rugth30.phys.rug.nl/compphys0/2001.htm"> K. Michielsen and
 H. De Raedt, "Integral-Geometry Morphological Image Analysis",<A0>
 Phys. Rep. 347, 461-538 (2001).</a>
 }}}

 where the "{{{<A0>}}}" is the Unicode no-break space character.  A simple
 workaround is
 to delete that character in
 {{{
 /opt/local/var/macports/build/_opt_local_var_macports_sources_github
 .com_macports_macports-
