Make fails in po directory

[Daniel Smith]

I get this error when I run "./configure; make" on a fresh download  
of 2.2.0.

Making all in po
cd .. \
   && CONFIG_FILES=po/Makefile.in CONFIG_HEADERS= CONFIG_LINKS= \
        /bin/sh ./config.status

I've built 2.1.5 via MacPorts, so all the dependencies should be  
installed correctly (including gettext 0.16.1).  I have not built  
manually (rather than via MacPorts) before, but I followed the  
instructions on the Wiki (MacOSX/MacPortsDetail), and declared these  
variables:

$ export CPPFLAGS="-I/opt/local/include"
$ export LDFLAGS="-L/opt/local/lib"
$ export DYLD_LIBRARY_PATH="/opt/local/lib"

This looks like some environment variable is perhaps missing, but I  
haven't been able to figure it out.  Any help would be appreciated.

My machine is a PowerBook G4 running OS X 10.4.10.
