you really should not even think about using ldd to show you a wrong list of possible dependencies, at least use lddtree or even better "scanelf -n" And unless you provide the needed details with either or both of above tools, there is not much to do here.
already found another user with more details, in short: -libsdl with USE=pulseaudio links against pulseaudio -e17 uses ecore, which uses libsdl -removing pulseaudio, while libsdl is built with support for it will break libsdl, so will break ecore, so will break e17, so simply dont do it.
