[R] Configuring R-2.10 help html server on Linux?

[Tom Wainwright]

Hi,

My Fedora 11 linux (version 2.6.30.9-96.fc11.x86_64 #1 SMP Wed Nov 4 00:02:04 
EST 2009) recently updated me to R-2.10.0, and help.start() is no longer 
working.  I see in the release notes that R now uses an internal web server to 
autogenerate help pages.  Here's what I'm getting:

IN R:

    > help.start()
    starting httpd help server ... done
    If '/usr/bin/xdg-open' is already running, it is *not* restarted, and
        you must switch to its window.
    Otherwise, be patient ...
    >

IN Firefox:

Firefox starts up, but gets a "connection refused" error:

    While trying to retrieve the URL: http://127.0.0.1:11586/doc/html/index.html
    The following error was encountered:
        * Connection to 127.0.0.1 Failed
    The system returned:
        (111) Connection refused

I have checked all my firewall settings, and as far as I can tell the connection 
should be allowed.  In fact, and unexpectedly, if I try on the command line:
	wget http://127.0.0.1:11586/doc/html/index.html
the index document is returned, so I know the R server is running OK on that 
port, but apparently refusing the connection to Firefox.

Has anyone else had a similar experience or have any wild guesses about a solution?
