Yeah your PATH probably doesn't include those. The execution environment
for a snap (even a devmode snap) is the core snap, which doesn't include
e.g. curl. The classic system on which you're presumably running is
mounted into var/lib/snapd/hostfs, I _think_ (zygmunt can answer with
more certainty).
