The modular build is invoked with:

	env LANG=C 	PATH=/Users/pete/Quellen/X11R7.1/util/modular:/usr/local/bin:/sw/lib/fontconfig2/bin:/sw/lib/freetype219/bin:/usr/local/ActivePerl-5.8.8/bin:/sw/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/gwTeX/bin/bin CFLAGS="-v -pipe -fPIC -O0 -mcpu=7450 -mtune=7450 -fno-common" CPPFLAGS="-v -no-cpp-precomp -I/usr/include/openssl -I/sw/include/pango-1.0 -I/sw/lib/freetype219/include -I/sw/lib/freetype219/include/freetype2 -I/sw/include/libpng12 -I/sw/include -I/usr/local/include" LDFLAGS="-dead_strip -bind_at_load -L/sw/lib/freetype219/lib -L/sw/lib/fontconfig2/lib -L/sw/lib/ncurses -L/sw/lib -L/usr/local/lib" ACLOCAL="/sw/bin/aclocal -I /usr/local/share/aclocal -I /sw/share/aclocal -I /usr/X11R7.1/share/aclocal" PKG_CONFIG_PATH=/sw/lib/freetype219/lib/pkgconfig:/sw/lib/fontconfig2/lib/pkgconfig:/sw/lib/qt4-x11/lib/pkgconfig:/usr/X11R7.1/lib/pkgconfig:/sw/lib/pkgconfig:/sw/share/pkgconfig:/usr/lib/pkgconfig:/usr/local/lib/pkgconfig util/modular/build1.sh -m /Users/pete/Quellen/Mesa-7.0.2 -D /usr/X11R7.1 -n

/sw/share/aclocal holds codeset.m4, gettext.m4, glibc21.m4, iconv.m4, isc-posix.m4, lcmessage.m4, and progtest.m4:

but I still have to read:

	Please add the files
	  codeset.m4 gettext.m4 glibc21.m4 iconv.m4 isc-posix.m4 lcmessage.m4
	  progtest.m4
	from the /aclocal directory to your autoconf macro directory
	or directly to your aclocal.m4 file.
	You will also need config.guess and config.sub, which you can get from
	ftp://ftp.gnu.org/pub/gnu/config/.

Mac OS X 10.4.11, /sw/bin/glib-gettextize (GNU glib) 2.12.12. The lines from glib-gettextize look so suspicious that I'll be going to report them to others too.
