configure.ac: not using gettext

I am trying to compile a gnome application and I am curious what the output means when I run the autogen.sh script: ~/Documents/Code/window-picker-applet $./autogen.sh autoreconf: Entering directory `.' autoreconf: configure.ac: not using Gettext autoreconf: running: aclocal autoreconf: configure.ac: tracing autoreconf: running: libtoolize --install --copy libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am. autoreconf: running: /usr/bin/autoconf autoreconf: running: /usr/bin/autoheader autoreconf: running: automake --add-missing --copy --no-force data/Makefile.am:11: `%'-style pattern rules are a GNU make extension data/Makefile.am:11: wildcard $(top_srcdir: non-POSIX variable name data/Makefile.am:11: (probably a GNU make extension) autoreconf: Leaving directory `.' [Output trunkated...] Why am I getting the info configure.ac: not using Gettext? Is that a warning and should I change some of the configuration files to fix it? I know the application has a po/ folder so I think it should be using Gettext, hence I am confused about this warning. I also had a lot of warnings with the N_ macro not being defined, so this might be related? **[Update]** See comment below **[/Update]**
