problems debugging scala program

I'm having some problems trying to debug a Scala 
(http://scala.epfl.ch/) program.  Here is my output:

VM loaded
Source for class not found. Check sourcepath. (Class: 
examples.testAuction)
VM running
Failed breakpoint resolution: examples auction.scala:127 (suspend all 
threads): There is no line number information for this class.
Current thread set to 1
VM running
Hit breakpoint 45
[main] testAuction$.main (auction.scala:127)
[main] testAuction$.main (auction.scala:128)
[main] testAuction$.main (auction.scala:129)

So you can see that on startup it complains about not finding the 
source for the breakpoints.  But when I resume the program it does in 
fact stop at my break points and allows me to step through the code.  
The main problem is that it will not let me set breakpoints while the 
VM is running.  It says "There is no line number information for this 
class", even though I am stepping line by line through the source code 
with no problems.  Thanks for any help!
