	# TODO: .so building seems to be broken currently (on amd64 atleast)

	# ./tag_tree_build: error while loading shared libraries: libdwarf.so: cannot open shared object file: No such file or directory
	# so it needs to be added temporarily to LD_LIBRARY_PATH, the emake line below doesn't work anymore though
	# fix?
