This is an unfortunately commonly seen message (also non-GRASS software).
Probably harmless. Do you observe any issues?

In Fedora they are gone - perhaps you need a newer GTK library version

I suppose to simply install them but I am not familiar with Linux Mint
(others here?).

Another option is to compile the code locally, some guide is here:
