[ap-utils] Mac OSX 10.3.3 build failure

[Scott Windsor]

I've been trying to build ap-utils with Mac OS X 10.3.3
does anyone know what the problem could be?
here's the output...

Making all in lib
if gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../intl    -g -O2 -MT ap_search.o 
-MD -MP -MF ".deps/ap_search.Tpo" \
   -c -o ap_search.o `test -f 'ap_search.c' || echo './'`ap_search.c; \
then mv -f ".deps/ap_search.Tpo" ".deps/ap_search.Po"; \
else rm -f ".deps/ap_search.Tpo"; exit 1; \
fi
