gtk3 @3.22.28+quartz: Package 'gl', required by 'epoxy', not found

Trying to install kde4-kile I get a fatal error while configuring gtk3 on macOs 10.13.3

main.log

The relevant error message is:

Package 'gl', required by 'epoxy', not found

A comment in the libepoxy portfile says:

# Yes, mesa and xorg-libX11 are *build* dependencies.  The library will function correctly
# if they are not present because it loads mesa dynamically only when GLX is used.  When
# OpenGL.framework is used, there is no need to have mesa at runtime.
#
# Clients of this library must link mesa directly and have it listed as their dependency
# in order to use mesa with libepoxy.

gtk3 always declares a dependency on libepoxy, but only declares a dependency on mesa when using the x11 variant, hence the problem, since you're using the quartz variant.

Thank you for your reply. Since I'm not an expert, could you please tell me which is a possible solution of this issue? Do I have to eliminate the quartz variant?
