trouble building on OpenBSD

[bonds]

In my attempt to build https://github.com/ssbc/patchwork on my OpenBSD box I ran into this error building node-spellchecker on which patchwork depends:

Well, duh:

node-spellchecker/binding.gyp

Lines 3 to 13 in edf4678

	'conditions': [
	['OS=="mac"', {
	'spellchecker_use_hunspell%': 'true',
	}],

	'spellchecker_use_hunspell': 'true',
	}],
	['OS=="win"', {
	'spellchecker_use_hunspell': 'true',
	}],
	],

...let's see what happens when I blindly enable OpenBSD there:

Ok, new error:

Is that progress? Not much. ;) FWIW hunspell, the executable, is installed and runs fine on my OpenBSD box. Maybe its installed with LibreOffice?
