executablePath not honored until some other shell command is issued

Platform: Mac OSX 10.11.6
Atom v1.9.9
linter-check 1.3.0
Other installed packages:
git-plus v5.16.2
grammar-token-limit 0.1.1
language-latex 0.6.1
latextools v0.8.2
linter 1.11.16

Have added to config.cson
'linter-chktex':
executablePath: "/Library/TeX/texbin/chktex"

I start the atom application and edit a latex file. When I go to save the file I get two alert boxes:

1. Failed to spawn command chktex. Make sure chktex is installed and on your PATH
2. Error: spawn chktex ENOENT
   at exports._errnoException (util.js:890:11)
   at Process.ChildProcess._handle.onexit (internal/child_process.js:182:32)
   at onErrorNT (internal/child_process.js:348:16)
   at _combinedTickCallback (internal/process/next_tick.js:74:11)
   at process._tickCallback (internal/process/next_tick.js:98:9)

If I build the latex file using latextools:build, modify the file and save again the linter-chktex package behaves as expected.
