That was the case.  Thanks.

Thanks for working with me Rob P.  Running /Applications/v0.3.24/Bitcoin.app/Contents/MacOS/bitcoin -server returns...

I would like to use the HTTP JSON-RPC and need to run the bitcoin server from my local machine (Mac OS X).

My setup varies from this question http://forum.bitcoin.org/index.php?action=printpage;topic=21956.0 in that my set up looks like the following...

I downloaded from here http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.3.24/bitcoin-0.3.24-macosx.zip/download

    -v0.3.24

        -block00001
        -blkindex.dat
        +database
        -db.log
        -debug.log
        -wallet.dat

From ~/Application Support/bitcoin/ if I run bitcoin -server I get bitcoin: command not found.  I also cannot find a bitcoin.conf file.  I am able to launch the GUI from my Applications folder.

What do I have to do to get the server running?  Thanks.
