That's talking about 'glib' which is not the same as 'glibc'.

Glib is a library from the GTK project which offers utility functionality related to the GTK widget toolkit, while glibc is the GNU C Library.

Amusingly, these kinds of beyond-the-core libraries are the ones that have always caused problems for me, never actual core GNU C Library.

glibc, not glib. That's a different library.

that's embarrassing.. you're right. Thank you for the correction. Wish I could delete my comment
