I had a problem with displaying correctly formatted code with this theme. The syntaxhighlighter decorates each token with <code> tag. It works fine unless something else defines style for code also. The theme does that. As the plugin is my primary formatter for the code, I just removed the style for the code tag from style.css file in pyrmont-v2 directory.
The removed code looks like that now:
/*div#main div.post div.entry code{*/
/*font-family: "Courier New", mono;*/
/*background-color: #181818;*/
/*border-left: 1px solid #2a2e2f;*/
/*color: #197b30;*/
/*padding: 5px 10px;*/
/*display: block;*/
/*}*/
Now any wp plugin based on syntaxhighlighter should work fine.

Thank You..
It really helpful..I already frustrated for 5 hours then I came to this blog and get satisfied.
The only thing that I should fix is the wrap text, it became a double lines in main source page :( do you have any idea with this?
Thank’s a lot.
There used to be an option to wrap/unwrap lines in syntax highlighter v2, but now it’s gone in version 3. Maybe playing a little bit with this can help you: http://bitbucket.org/alexg/syntaxhighlighter/issue/182/version-3-making-code-wrap.
