Comment (by ballapete):

 I am building once more watching in another window of GNU Emacs what is
 happening in
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports
 .org_macports_release_tarballs_ports_x11_xorg-libxcb/xorg-
 libxcb/work/libxcb-1.15/doc/manual. It seems that 1888 DOT files à la
 `inherit_graph_<#>.dot` are converted into PNG, MAP and MD5 formats. After
 conversion the DOT file is deleted. The process started at 12:13 h and
 seems to have some endurance …
