Steps to reproduce:

1. Install (eg.) ImageMagick's "compare" in /usr/local/bin.
2. Install AraxisMerge.
3. Set up AraxisMerge as an "External Diff / Merge" under Preferences... > Diff
4. Create a merge conflict in a repository.
5. Right click and Resolve Merge Conflicts > Launch External Merge Tool
6. Nothing happens.

This is because of the following:

• araxiscompare-w.sh

  export PATH=~/bin:/usr/bin:/bin:/Applications/Araxis\ Merge.app/Contents/Utilities
  

• araxisgitmerge-w.sh

  export PATH=~/bin:/Applications/Araxis\ Merge.app/Contents/Utilities:/usr/local/bin:/usr/bin:/bin:$PATH
  

• araxishgmerge-w.sh

  export PATH=~/bin:/usr/local/bin:/usr/bin:/bin:/Applications/Araxis\ Merge.app/Contents/Utilities:$PATH
  

The current workaround is to change these scripts and place Applications/Araxis\ Merge.app/Contents/Utilities before /usr/local/bin
