mkdir: /Users/rkmax: Permission denied

Ideally those lines should be updated from

project_dir=/Users/rkmax/development/aseprite
skia_dir=/Users/rkmax/development/skia

to

project_dir=/Users/$(whoami)/development/aseprite
skia_dir=/Users/$(whoami)/development/skia

But at a minimum just replace rkmax on lines 6 & 7 with your own username
