Comment (by devans@…):

 From your log file, gtkdoc-fixxref (a perl script provided by gtk-doc) is
 failing as follows:
 {{{

 The pertinent lines in gtkdoc-fixxref are as follows:
 {{{
     # write source to a temp file
     my $temp_source_file="$MODULE_DIR/_temp_src.$$.h";
     open (NEWFILE, ">$temp_source_file") || die "Can't open
 $temp_source_file: $!";
     print NEWFILE $source;
     close (NEWFILE);

     # format source
     system "echo 'let html_number_lines=0|let html_use_css=1|let
 html_use_xhtml=1|syn on|e $temp_source_file|run! syntax/2html.vim|w!
 $temp_source_file.html|qa!' | /usr/bin/vim -n -e -u NONE -T xterm
 >/dev/null";

     my $highlighted_source;
     {
         local $/;
         open (NEWFILE, "<$temp_source_file.html");
         $highlighted_source = <NEWFILE>;
         close (NEWFILE);
     }
     $highlighted_source =~ s#.*<pre\b[^>]*>\n##s;
     $highlighted_source =~ s#</pre>.*##s;

     # need to rewrite the stylesheet classes
     # FIXME: Vim has somewhat different syntax groups
     $highlighted_source =~ s%<span class="Comment">%<span
 class="comment">%gs;
     $highlighted_source =~ s%<span class="PreProc">%<span
 class="preproc">%gs;
     $highlighted_source =~ s%<span class="Statement">%<span

     $highlighted_source =~ s%<span class="Identifier">%<span

     $highlighted_source =~ s%<span class="Type">%<span class="type">%gs;

     # remove temp files
     unlink ($temp_source_file)
         || die "Can't delete $temp_source_file: $!";
     unlink ("$temp_source_file.html")
         || die "Can't delete $temp_source_file.html: $!";
 }}}

 Comparing the two, it looks like the current source being processed is
 copied to a temp file (html/_temp_src.2792.h) and then a system command is
 executed that uses /usr/bin/vim to format it and save the result in
 html/_temp_src.2792.h.html.  From the error messages, it looks like the
 first file is being created but the second is not.

 Does /usr/bin/vim exist on your system? Is there an error in system.log at
 the failure point that might shed more light on the what's happening?
