I want to install loaddap. I downloaded an rpm from
http://opendap.org/download/ml-structs.html.

# yum --nogpgcheck localinstall loaddap-3.6.1-1.x86_64.rpm

Apparently my libdap is too old:
# rpm -q libdap
libdap-3.7.8-1.el5.1

And it is current with the centos repos,
# yum update libdap

No Packages marked for Update

so I need a good rev source rpm
