Flex ant task problem

When I try to build a project that uses Flex and where the Flex SDK is on one drive and the project files on another I get the following error in ant: [mxmlc] java.lang.NoClassDefFoundError: flex2/tools/Compiler [mxmlc] Exception in thread "main" It seems to be a problem with the Flex mxmlc ant task. Anyone know the root cause of this? It works if I move the Flex SDK over to the project folder but I don't like being hackish like that... Ant in verbose mode gives: compile.main: dropping E:\c from path as it doesn't exist dropping E:\programs\flex-sdk\lib\mxmlc.jar from path as it doesn't exist [mxmlc] java.lang.NoClassDefFoundError: flex2/tools/Compiler [mxmlc] Exception in thread "main" [antcall] Exiting E:\svn\trunk\dev\modules\web\webapps\lpjserver\lpjserver-build.xml.

It looks like there is a bug in the private void executeOutOfProcess() method of the FlexTask.java Flex ant task. It seems to be using a reference to one file to get the absolute path then use that path to access other things. I really don't want to spend any more time on it right now so leaving at that.
