[Building Sakai] Getting NullPointerException testing source build of 2.7.1

Hi,
.  
I built Sakai 2.7.1 from source using Maven 2.2.1 and then installed same in
Tomcat 5.5.31.  The System runs on Redhat ES 5.   I followed the install
from source instructions on the Sakai Project website (URL:
http://confluence.sakaiproject.org/display/DOC/Sakai+2.7), including setting
java_opts within Tomcat, etc.  I also tailored a sakai.properties file so as
to include a proper URL and title.  I assume that ³By default, all Sakai
distributions are configured to use an in-memory version of HSQLDB² means
that I can leave database configuration alone at least until I¹ve tested
everything.

Here¹s the problem.  I created a new user, me, and I also created a new
worksite and within that worksite I added a portfolio.  For the portfolio, I
chose Simple HTML and added a page containing only the line ³My Portfolio².
When I clicked on the link to view the portfolio, the response was ³An
unexpected error has occurred.²  And along with that, a lengthy StackTrace
(included below).

This is my first time playing with Sakai, so I¹m not sure what other useful
information I can provide.  Any idea why I¹m getting the exception?

Thanks,
