I use gvim with dev-util/global’s gtags-cscope. It works just fine, assuming [g]vim was built with USE=cscope. However, USE=cscope pulls in dev-util/cscope as a dependency, and this is not necessary if using dev-util/global. IMO it ought to be || ( dev-util/cscope dev-util/global ). Also I don’t think these are needed at compile time, so could be in RDEPEND but not DEPEND, if you feel like changing that.
