Update to proftpd fails when using Webmin update

I've had an update for proftpd that I haven't been able to install for a while now. Here's the output I get when I try to run it:

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
.. install failed!

I've run the commands suggested from the command line connected by ssh and they haven't fixed anything. I can't figure out how to fix this dependency issue. Any suggestions would be appreciated. I've had other updates that go through normally, so this is sort of a one-off issue as far as I can tell.
