Comment (by barracuda156):

 `cairo-devel` is broken for old Xcode gcc at the moment. It does build
 with `gcc13`, but that breaks its dependents (perhaps revbumping gonna be
 required). I.e. once `cairo-devel` is activated, I get this with every
 GTK-using port:
 {{{
 36-231% claws-mail

 (claws-mail:85907): Gdk-ERROR **: 14:34:06.835: The program 'claws-mail'
 received an X Window System error.
 This probably reflects a bug in the program.
 The error was 'BadAccess (attempt to access private resource denied)'.
   (Details: serial 194 error_code 10 request_code 133 (unknown) minor_code
 1)
   (Note to programmers: normally, X errors are reported asynchronously;
    that is, you will receive the error a while after causing it.
    To debug your program, run it with the GDK_SYNCHRONIZE environment
    variable to change this behavior. You can then get a meaningful
    backtrace from your debugger if you break on the gdk_x_error()
 function.)
 zsh: trace trap  claws-mail
