I'd be happy to help. Let me know what info you'll need, and I'll
assemble it.

I set CLASSPATH in the shell environment before launching eclipse:
export CLASSPATH="pathtoX10runtime.jar"
./eclipse
The JAR file does appear in the build path libraries. The error log
contains the following (note that the X10 runtime.jar is the second item
in the class path):
