Comment:

 Yes, the problem the patch solves (gi18n.h uses `#include <libintl.h>` so
 the path to libintl.h needs to be provided in the compile flags; see
 #9937) is still relevant; see comment:ticket:55577:3.

 comment:ticket:55577:4 suggests an alternate fix for the problem: instead
 of adding `-I/opt/local/include` to Cflags in glib-2.0.pc, patch the two
 files that `#include <libintl.h>` to so that they `#include
 </opt/local/include/libintl.h>` instead. While disagreeing with the
 premise that ports should not use `-I/opt/local/include` or provide .pc
 files that do so, I'm willing to make this change because it is a less
 invasive solution to the problem.
