Gettext error while "make update-po"

I have followed this guide, but when I try to do "make update-po" i get following erro开发者_JAVA百科r:

make: *** No rule to make target `update-po'. Stop.

Do you know how to fix it?

When you run configure, does it tell you somewhere in its long list of output, that natural language support (NLS) is "enabled" or "disabled"? If disabled, then the makefile rules are also not output.
