I'm not familiar with heimdal and I have no idea why php5 is trying  
to use heimdal for kerberos support since the php5 portfile says:


Does /opt/local/lib/libcom_err.1.dylib actually exist on your system?  
As you saw from the error message, /opt/local/lib/libkrb5.dylib was  
unable to open it. Perhaps you just need to rebuild heimdal.

Perhaps heimdal needs to be updated. Version 0.8.1 has been available  
since April 2007. I'm Cc'ing the maintainer.
