gnu-classpath

I've got an unusual build error when using Buildroot to create an image for my Phidget SBC. It's unusual because it occurs ONLY on my development laptop and NOT on my general use laptop even though I am using EXACTLY the same Builroot environment as published by Phidgets themselves.

When I try to create my Buildroot image I get the following error when it attempts to compile GNU classpath:

Making all in tools
make[2]: Entering directory `/home/xxxx/buildroot_phidgetsbc/buildroot-phidgetsbc_1.0.4.20111028/output/build/classpath-0.98/tools'
/bin/mkdir -p classes asm 
/bin/mkdir -p ../tools/generated/gnu/classpath/tools/gjdoc/expr
java -classpath  antlr.Tool -o ../tools/generated/gnu/classpath/tools/gjdoc/expr/ \
      ./gnu/classpath/tools/gjdoc/expr/java-expression.g

Unrecognized option: -o
Could not create the Java virtual machine.
make[2]: *** [tools.zip] Error 1

The only difference I can possibly thing of is the different Linux (Ubuntu) versions I am using on each laptop. Also I cannot find a -o option documented for Java and don't understand why it works on one laptop but not the other.

Any suggestions would be helpful.
