bigfoot and footmisc do not work well together with “multiple” option

I would like the footnotes from the example to appear comma-separated where they are referenced in the text. The "multiple" option of footmisc should be able to do this, but it does not work. How can I make it work? Am I loading the packages wrongly?

thanks james

MWE:

\documentclass{article}
\usepackage[multiple]{footmisc}
\usepackage{bigfoot}

\DeclareNewFootnote[para]{R}[Roman]
\DeclareNewFootnote[para]{N}

\begin{document}
First sentence.\footnoteR{Here is a footnote.}\footnoteR{Here is another footnote.}\footnoteN{And another one.}\footnoteN{And moe.} And another one.
\end{document}

I don't think that footmisc can cope with new footnote types defined with bigfoot commands. –  egreg Jul 7 '12 at 19:27

The fnpct package does handle this correctly:

\documentclass{article}
\usepackage[
paperwidth=.5\textwidth,
paperheight=12\baselineskip,
margin=5pt,
bottom=1.5cm]{geometry}
\usepackage[dont-mess-around]{fnpct}[2012/07/07] % v0.2d
% the dont-mess-around' option disables additional kerning
% and punctuation switching.
\usepackage{bigfoot}

\DeclareNewFootnote[para]{R}[Roman]
\DeclareNewFootnote[para]{N}

\begin{document}
First sentence.\footnoteR{Here is a footnote.}\footnoteR{Here is another footnote.}%
\footnoteN{And another one.}\footnoteN{And moe.} And another one.
\end{document}

Many thanks. I will try to install this package to my Latex installation on OS X and try it out. Would be great if it works! –  james Jul 9 '12 at 10:19
