I installed realvnc.tce and tried to start it per the man page. I looked around for it but could not find where it was installed. Looks like it needs environment variables set among other things.
-----------------------
edit: Ok realvnc installs vnc4xxxxx programs in /usr/local/bin. Looks like there is an unresolved dependency with perl so I installed the perl extension which then enabled "vnc4server start" to run and complain vncpasswd must be run to setup the password which is what the man page says will happen so that's good. However, after I set the password the vnc4server would not start due to an error about "couldn't find "vncpasswd" on your PATH. Not sure how to fix this so will try this another day.
