Tim, The "cmake" step now requires static libxml2 installed, otherwise it fails - not a problem, just something people should be aware of. The output when lixml2.a is absent is attached - cmake.out;
The bigger problem is, even after I install static libxml2 the compilation step fails for me. I'm attaching make.out output of "make".
