$ ls -l  /usr/bin/pod2html*
-rw-rw-rw-  37 root  wheel   811 10 Sep  2014 /usr/bin/pod2html
-rwxr-xr-x   1 root  wheel  2073 10 Sep  2014 /usr/bin/pod2html5.16
-rwxr-xr-x   1 root  wheel  2073 10 Sep  2014 /usr/bin/pod2html5.18

The file located at /usr/local/bin/pod2html path clearly states:
-- cut --
The contents of this script should normally never run!  The perl wrapper
should pick the correct script in /usr/bin by appending the appropriate
version.
You can try appending the appropriate perl version number.  See perlmacosx.pod
for more information about multiple version support in Mac OS X.

I believe this is an issue with assumption in cfe/clang/docs/tools/Makefile,
that pod2html is accessible (with exactly this name).

It builds when /usr/bin/pod2html5.18 is symlinked to pod2html (symlink earlier
in path).
