chmod changes not getting noticed/committed by svn

I have some executable binries in a linux project I manage with IntelliJ 10.5.

I noticed the binaries would not execute when I pulled the project.

So I went to the command line and made the chmod change (777, natch.)

But, this change won't get picked up as a change by intelliJ svn, so I cannot commit this change.

Any suggestions as to how to address this problem so that svn notices this change and commits the change.

Thanks,
Erik
