Just to clarify what exactly is controversial or difficult and has to be done. The *.java files under src/hep/aida/ in Colt belong to the freehep-aida project at http://aida.freehep.org/ and are licensed under LGPL-2.1. I have checked out the CVS repository and the source files are accompanied by the full LGPL license in LGPL.txt. No signs of exceptions. The files under src/hep/aida/ref can be traced back to freehep-jaida http://java.freehep.org/jaida/. The source files are located in a SVN repository: svn checkout svn://svn.freehep.org/svn/freehep/trunk/jaida jaida See freehep-jaida/src/main/java/hep/aida/ref It looks like most of them are very similar to the ones you can find in colt. All jaida files are also licensed under the LGPL-2.1. That leaves src/hep/aida/bin where I couldn't find correspondent files on freehep.org. That means you probably have to remove the whole directory and try to recompile colt. Every class that imports "hep.aida.bin" will need a patch or has to be excluded as well. I have not verified how Apache Mahout can replace the affected functionality and whether it is possible at all. So far Markus
