samba - Feb 2008 - unable to compile samba 3.0.28 on Centos 5 64-bit

I downloaded and extracted samba-3.0.28.tar.gz and went to 
samba-3.0.28/packaging/RHEL and ran sh makerpms.sh and it compiles for a 
while and then I get the following error.  Any ideas on what to try?  
The server is X86_64 running CentOS 5 X64.
