Strange compile error in 977

I am getting the following error when I try to do a make or rebuild project in build 977:

Information: 1 error
Information: 0 warnings
Error: javac: invalid argument: C:/dev/Trunk/emktg/src/java/meredith/commerce/checkout/.

Information: Compilation completed with 1 errors and 0 warnings
Information: -deprecation Output source locations where deprecated APIs are used

I'm assuming I've got something configured incorrectly. It was working before I installed 977.
