Hi Greg,

I cloned the repo and have built it. The tests (make test) fail to
compile/run, but the code works flawlessly. I tried maven.git,
maven-intergration-testing.git, maven-scm.git, maven-wagon.git and other
crucial components (from Codehaus Plexus). They all compile and pass
flawlessly. I will additionally try several native ones like Hawt JNI,
Commons Daemon and Tomcat Native.

Thank you very much for the fix!

Michael
