Cannot register transform lynx_dump error log entries in Plone 4

Question

Currently one of Plone 4.1 instance.log is (mgirated from 3.3) gets messages like:

2012-07-09 17:40:38 ERROR PortalTransforms Cannot register transform lynx_dump, using BrokenTransform: Error
 Unable to find binary "lynx" in /Users/moo/tools/bin:/Users/moo/.zsh/bin:/opt/local/libexec/gnubin:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

1) Is this a real error (probably not)?

2) How to get rid of this messages?

Answer 1

It is not a real problem, unless you use the lynx_dump transform (nothing in stock Plone uses it, and other transforms provide text/html to text/plain too).

You have two options to deal with it:

1. Remove the lynx_dump transform. Go to the ZMI, find the portal_transforms tool, check the box by the lynx_dump entry, and hit the [Delete] button at the bottom of the form. This is harmless if you don't use the transform.

2. Install the lynx command. port install lynx should do.
