 I have my MacPorts installed as a non-root user in the prefix /mp, and
 cotvnc doesn't like this:

 {{{
 $ port install cotvnc
 --->  Fetching cotvnc
 --->  Verifying checksum(s) for cotvnc
 --->  Extracting cotvnc
 --->  Configuring cotvnc
 --->  Building cotvnc
 --->  Staging cotvnc into destroot
 --->  Installing cotvnc @2.0b4_0
 Error: Target org.macports.install returned: can't create directory
 "/mp/var/macports/software/cotvnc/2.0b4_0/Applications/MacPorts/Chicken of
 the VNC.app/Contents": permission denied
 Error: Status 1 encountered during processing.
 $
 }}}

 Many other ports seem not to like this either. I've had to apply patches
 to CronniX, osxvnc, SSHKeychain...

 It looks like r22902 was supposed to solve this maybe but it didn't
 completely. The patch I attach fixes it for me.
