I built it but can only find the core jar file, nothing for the
compiler. With just the core jar replaced, I still get the NPE.

Nope, only source code.
Problem is 4.0.x will be released as 4.0.7, and if your specific
problem is fixed and you are not able to test before the release, it
will have to wait 4.0.8. <http://4.0.8.>
All you need to build drools is java, maven and ant. Can you set
this up?

Glad to hear that. However, I am not set up to do my own drools
build and it looks like the link you sent is for the source. Is
there a set of jars for 4.0.x that I can test from? Here is what I
am using now:
antlr-runtime-3.0.jar
core-3.2.3.v_686_R32x.jar
drools-compiler-4.0.4.jar
drools-core-4.0.4.jar
mvel14-1.2.21.jar
xstream-1.2.2.jar
Thanks,
Scott
