Can confirm. Let's see if I can fix as well.

Adding bundler inline breaks the detection of the ruby runtime in systemu (those two /home/.../Gemfile not foundlines are the two system calls in lines 38 and 41. Both fail so systemu says it can't find a ruby.

Basically this happens without systemu being involved. I can reduce the problem to calling ruby with system after requiring bundler/inline:

require 'bundler/inline'
gemfile do
    source 'https://rubygems.org'
end
c = ::RbConfig::CONFIG
ruby = File.join(c['bindir'], c['ruby_install_name']) << c['EXEEXT']
system(ruby, '-e', '42')

I don't see how I can work around this yet.
