vmware-guestd daemon is for time synchronization with host OS and others. Beware, this port is for FreeBSD _guest_ OS. You don't need to install this ports to FreeBSD _host_ OS. This ports also installs a kernel modules for FreeBSD guest. If you want to run FreeBSD as a VMware guest OS, install this port would help you. If you want to run X, install vmware-tools too. This port assumes that a) users want only "must-have" binaries and b) guest OS runs on a certain architecture and never be changed. For those want full-feature of VMware Tools, use the installer bundled with VMware Tools instead. WWW: http://www.vmware.com/products/ws/
