I found the problem. OpenSSH and ssh.com use different formats for
their keys... ssh-keygen -e -f changes the public key into something
ssh.com can handle.

[CLIENT rt]$ ssh-keygen -e -f .ssh/id_dsa.pub > .ssh/id_dsa_ssh.pub
[CLIENT rt]$
scp .ssh/id_dsa_ssh.pub prl2@remote.name.edu:/home/prl2/.ssh2/rt_dsa.pub

Thanks!
