Hi Andreas, Here's my take on mugsy issues. I worked on a tree checked out with: $ svn checkout svn://svn.code.sf.net/p/mugsy/code/trunk mugsy-code Building with gcc-4.9.2. The version of boost I compiled it against is 1.56. I couldn't get it to link, because the authors apparently never heard of autotools. Generally, those handwritten Makefile's just.. made me cry. Hope this helps, Andrei
