ant problems with 6.01

In IDEA 5, my ant files have no errors or warnings. In IDEA 6, it is a
see of red. If I hover the mouse on one of the errors, the tooltip says
something like:

File
'c:\progra_1\jetbra1\intell~1.0\bin\.\${env.SOME_VAR}/java/config/dev.properties'
does not exist

On my Linux machine I see the same behavior, but the error tooltip says:

File
'/home/me/apps/idea-5784/bin/./${env.SOME_VAR}/java/config/dev.properties'
does not exist

When I run any of the targets in the ant file, it works fine. Any ideas?
