I'm trying to build X11R7.0 on Crux v2.1 linux distribution and I get stuck with the below error.  Can anyone lend some advice on what i'm missing from my autoconf configurations that's preventing the macros from loading, as shown below?  I checked all my autoconf, automake, m4, etc versions and they're all above the min levels.  I also installed by hand the latest pkg-config tool from <a href="http://freedesktop.org">freedesktop.org</a>, and libtool and gettext from <a href="http://gnu.org">gnu.org</a>.  I've tried several of the programs under x/lib/ and get the same result, so i'm sure it's local to my machine, but i just don't know enough about configure to figure it out... thanks # pwd /root/x/lib/Xau # ./autogen.sh autoreconf: Entering directory `.' autoreconf: <a href="http://configure.ac">configure.ac</a>: not using Gettext autoreconf: running: aclocal autoreconf: <a href="http://configure.ac">configure.ac</a>: tracing autoreconf: running: libtoolize --copy libtoolize: `config.guess' exists: use `--force' to overwrite libtoolize: `config.sub' exists: use `--force' to overwrite libtoolize: `ltmain.sh' exists: use `--force' to overwrite autoreconf: running: /usr/bin/autoconf autoreconf: running: /usr/bin/autoheader autoreconf: running: automake --add-missing --copy --no-force autoreconf: Leaving directory `.' checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for gawk... gawk checking whether make sets $(MAKE)... yes checking whether to enable maintainer-specific portions of Makefiles... yes checking for gcc... gcc checking for C compiler default output file name... a.out checking whether the C compiler works... yes checking whether we are cross compiling... no checking for suffix of executables... checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ANSI C... none needed checking for style of include used by make...
