Android build.xml renderscript doesn't support includepath
===

I'm running my android project using ant in order to continuously run it using Hudson.  I have created my build.xml on my mac and instead of importing the generated android build.xml, I copy/pasted it in, since I have to customize some things.  

It works fine on my local machine, however, when I run this on hudson, located on a server.  I run into an error with the Renderscript attribute.  
    
    renderscript doesn't support the "includePath" attribute

So, I decided to take OUT that line in the xml transforming this code:

     <renderscript executable="${renderscript}"
                  	includePath="${android.renderscript.include.path}"
                    genFolder="${gen.absolute.dir}"
                    resFolder="${out.res.absolute.dir}/raw"
                    targetApi="${project.minSdkVersion}"
                    optLevel="${renderscript.opt.level}"
                    buildType="${build.is.packaging.debug}"
                    previousBuildType="${build.last.is.packaging.debug}">
                <source path="${source.absolute.dir}"/>
            </renderscript>

to this:

     <renderscript executable="${renderscript}"
                    genFolder="${gen.absolute.dir}"
                    resFolder="${out.res.absolute.dir}/raw"
                    targetApi="${project.minSdkVersion}"
                    optLevel="${renderscript.opt.level}"
                    buildType="${build.is.packaging.debug}"
                    previousBuildType="${build.last.is.packaging.debug}">
                <source path="${source.absolute.dir}"/>
            </renderscript>

And then comically get this error:

    RenderScriptTask's 'includePath' is required.



I'm running the same ant on both machines, downloaded the linux-specific SDK on the server, updated based on tools, platform-tools, and android-7 (the OS I'm supporting).  I've run out of ideas of what the problem could be, any help or pointers would be amazing.

Thanks!
