vimproc not working on Acer C720 Chromebook: E364: Library call failed for "vp_pty_open()"

[mike-pomodoro]

I've followed the vimproc install steps on a Ubuntu VM and it works fine, but the same install steps do not work on Chrome OS. It appears vimproc is not compatible with Chrome OS.

This fails on my Google Chrome OS Acer C720 laptop:

:VimProcBang pwd

With error:

E364: Library call failed for "vp_pty_open()"

And with error:

[vimproc] Your vimproc binary is not compatible with this vimproc!

The laptop is a Chromebook running this Chrome OS version:

Version 52.0.2743.85 (64-bit)
Platform 8350.60.0 (Official Build) stable-channel peppy
Firmware Google_Peppy.4389.93.0

The laptop's been put into Developer mode and Chromebrew has been installed to allow building and installing general Linux applications.

The Linux kernel installed on this laptop:

(env) chronos@localhost ~/.vim/bundle/vimproc.vim$ uname -a
Linux localhost 3.8.11 #1 SMP Wed Jul 20 21:28:49 PDT 2016 x86_64 Intel(R) Celeron(R) 2957U @ 1.40GHz GenuineIntel GNU/Linux

VIM is version 7.4:

(env) chronos@localhost ~/.vim/bundle/vimproc.vim$ vim --version
VIM - Vi IMproved 7.4 (2013 Aug 10, compiled Jul 28 2016 23:21:04)

The error when executing:

:VimProcBang pwd
