Hi, Just for quicks I thought I'd try building Ardour2. I see a new library is required called 'boost'. I'm wondering about the proper USE flags for this. Do I want or not want to use the 'threads' flag? [ebuild N ] dev-libs/boost-1.33.1 USE="-bcp -bjam -debug -doc -pyste -static -threads -threadsonly" 11,237 kB Thanks in advance. - Mark
