gtk2 @2.12.9_0 does not permit +quartz

[sfiera@…]

gtk2 was updated in [36184] to add a no_x11 variant. Its pre-fetch reads as follows:

if {[file exists ${prefix}/lib/libpangox-1.0.dylib]} {
    ui_error "Please uninstall or deactivate the pango port and reinstall it by running `port install pango +no_x11`."
}
error "pango must be installed with the no_x11 variant enabled."

It seems like that this was intended:

if {[file exists ${prefix}/lib/libpangox-1.0.dylib]} {
    ui_error "Please uninstall or deactivate the pango port and reinstall it by running `port install pango +no_x11`."
    error "pango must be installed with the no_x11 variant enabled."
}

Since the existing version prevents gtk2 +quartz from being installed, even in when pango +no_x11 is. An attached patch will make the aforementioned change.
