>Description:
Various scripts installed by pkgsrc/devel/scmgit tries to execute /usr/pkg as a 
script: "exec: /usr/pkg: permission denied". Guess some paths are wrong?
>How-To-Repeat:
% mkdir test
% cd test 
% git init
Initialized empty Git repository in .git/
% gitk
exec: /usr/pkg: permission denied
% git-gui
exec: /usr/pkg: permission denied
