picotool version check uses system path even when PICOTOOL_FETCH_FROM_GIT_PATH set
I have two version of picotool available in my ~/pico directory: picotool-2.1.0 and picotool-2.1.1. Setting environment variable PICOTOOL_FETCH_FROM_GIT_PATH according to documentation should set which picotool to use but this always checks the version in /usr/local/bin/ and not the path pointed to by PICOTOOL_FETCH_FROM_GIT_PATH.
Could you please clarify the exact paths to your picotool executables, and what you've been setting your PICOTOOL_FETCH_FROM_GIT_PATH variable to?
Also, just to clarify, PICOTOOL_FETCH_FROM_GIT_PATH should be set to an empty directory which the SDK will then clone and build picotool in - it should not be set to an existing picotool clone that you’ve created (which would probably cause the issue shown here)
Yes the directory isn't empty it is the project folder for the version 2.1.1 of Picotool. PICOTOOL_FETCH_FROM_GIT_PATH=/Users/jondurrant/pico/picotool-2.1.1
In previous SDK version this was the approach to providing a consistent copy of picotool that can be used across projects. How do we now configure the project not to rebuild picotool?

Just to conclude this issue - this is what's causing the problem. If you want to use PICOTOOL_FETCH_FROM_GIT_PATH then you have to point it at an initially empty directory that the SDK will populate. You can then point this and any other projects at this using the same PICOTOOL_FETCH_FROM_GIT_PATH.
If you want to force fetching from git to ensure it never uses the system path, then you can set PICOTOOL_FORCE_FETCH_FROM_GIT
However, the recommended approach is to build and install picotool separately, as described in the picotool readme
