generating configuration files
------------------------------

configure: creating ./config.status
config.status: creating Makefile
config.status: creating src/Makefile
config.status: creating libstemmer_c/Makefile
config.status: creating sphinx.conf.dist
config.status: creating sphinx-min.conf.dist

config.status: config/config.h is unchanged
config.status: executing depfiles commands

configuration done
------------------

You can now run 'make' to build Sphinx binaries,
and then run 'make install' to install them.

All fine, as far as I can tell. But when I run make, I get this:

Making all in src
if test -d ../.svn; then svn info .. --xml | perl svnxrev.pl; fi;
make all-am
if g++ -DHAVE_CONFIG_H -I. -I. -I../config -DSYSCONFDIR="\"/usr/local/sphinx/etc\"" -I/usr/local/include -I/usr/include -fno-omit-frame-pointer -pipe -D_P1003_1B_VISIBLE -DSIGNAL_WITH_VIO_CLOSE -DSIGNALS_DONT_BREAK_READ -DIGNORE_SIGHUP_SIGQUIT -Wall -g -D_FILE_OFFSET_BITS=64 -O3 -DNDEBUG -MT sphinx.o -MD -MP -MF ".deps/sphinx.Tpo" -c -o sphinx.o sphinx.cpp; \
then mv -f ".deps/sphinx.Tpo" ".deps/sphinx.Po"; else rm -f ".deps/sphinx.Tpo"; exit 1; fi

I'm running Mac OSX Server
MySQL Ver 14.12 Distrib 5.0.82, for apple-darwin9.0 (i386) using EditLine wrapper

Any ideas?
