Thanks for the heads up.

I'm not sure what's happening here: polyglot-groovy-0.4.11.jar was 
indeed split away from "libtakari-polyglot-maven-java" and into 
"libtakari-polyglot-groovy-java", however the new version of 
"libtakari-polyglot-maven-java" does *not* depend on/recommend 
"libtakari-polyglot-groovy-java".

So I'm unsure why "libtakari-polyglot-groovy-java" is being installed in 
the first place, during the piuparts upgrade. It's not present in 
testing, and it has currently zero reverse-dependencies.

I did my own testing and on a bare system with 
"libtakari-polyglot-maven-java" installed, upgrading to sid does not 
include an installation of "libtakari-polyglot-groovy-java".

Any idea what's going on?

Thanks,
