LGBI. The build error on Linux and GTK3 seems to only appear on Travis CI environment.
Nah it's my bad, dddd4bcc0ee5c756e08b3cffa13bdf43cad2ba1c removes the check for whether Scope is enabled because I thought it was redundant but didn't realize this conditional was in utilslib…
…which IMO is a very bad thing. BTW, as is I doubt the vtecompat thing in utilslib makes much sense, because it seems highly specific to Scope's use of it, but well.
Anyway, the test should be in the corresponding module, so as it's in utilslib it should be in the utils checks. I did that in the latest version of this PR.
