What is the one machine not running Guix?  GNU Linux or something else?

If the other machine is not running Guix but still GNU linux, you can
use “guix pack -RR” and then point the executable to the right location.

  /path/to/relocate/bin/unison
  

If this does not work, and you cannot change the Unison on the other
machine, you can always roll-back to your previous unison.  Somehow,

  guix time-machine --commit=<commit> -- install unison -p /path/to/

where <commit> is the last commit with an Unison working.  Then,

   /path/to/profile/bin/unison


Hope that helps,
