do-install target is running. So use installed vmware-guestd to detach
VMware Tools CD-ROM (same as ports/emulators/vmware-guestd/Makefile rev 1.3.)
No content change will apply with this commit.
- Extracts tarball from (pseudo) CD-ROM directly.
- RUN_DEPENDS to vmware-guestd which is newly added.
- Install XF86_VMware X server if and only if XFREE86_VERSION=3.
- Some cosmetics.
