Contributor UI error: NoSuchMethodError fatwire/ui/controller/controller

Question

Hi All,
I performed a full installation of 11g today, with Oracle DB and WebLogic (all on Windows Server x64).
All has seemed to go well, excepting that the new Contributor UI does not render - the new contributor area is blank. I've tried IE and Firefox and the sample apps FirstSite II and Avisports.
Reviewing the logs the below exception is thrown. The fatwire/ui/controller/controller.jsp is present when using ContentExplorer to check.
[2012-06-12 16:55:13,330] [ERROR] [.kernel.Default (self-tuning)'] [fatwire.logging.cs.jsp] java.lang.NoSuchMethodError: org.apache.commons.lang.exception.ExceptionUtils.getMessage(Ljava/lang/Throwable;)Ljava/lang/String; for pagename=fatwire/ui/controller/controller&ft_ss=false
javax.servlet.ServletException: java.lang.NoSuchMethodError: org.apache.commons.lang.exception.ExceptionUtils.getMessage(Ljava/lang/Throwable;)
Does anyone have any advise please?
Thanks

From the installation guide (Page 43: Setting CLASSPATH and PRE_CLASSPATH):
For the WebCenter Sites Contributor interface to load properly, edit the setDomainEnv.cmd file under the <domain_home>/bin directory and add the commons-lang-2.4.jar file, used by WebCenter Sites, to the PRE_CLASSPATH as follows:
set PRE_CLASSPATH=<webapplication_stage_directory>/<webcenter_sites_webapplication>/WEB-INF/lib/commons-lang-2.4.jar
