the tightvnc ebuilds depend on xfree directly, so try to pull it in when xorg-x11 is installed. Reproducible: Always Steps to Reproduce:
I created a new ebuild for tightvnc in my PORTDIR_OVERLAY and just changed the ">=x11-base/xfree-4.2.1" dependency for "virtual/x11" and it seems to work fine.
Same problem here. It should depend on virtual/x11
fixed in cvs
