hello,

i've receive a raspberry pi 2. Gem is not installable via apt-get, so i'm trying to compile it.

i get the source from https://github.com/umlaeute/Gem

the compilation procedure fail on the 1st step :

pi@raspberrypi ~/Gem $ ./autogen.sh PATH: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games AUTORECONF: /usr/bin/autoreconf AUTOHEADER: /usr/bin/autoheader AUTOMAKE : /usr/bin/automake ACLOCAL : /usr/bin/aclocal LIBTOOL : /usr/bin/libtool LIBTOOLIZE: /usr/bin/libtoolize AUTOCONF : /usr/bin/autoconf running autoreconf autoreconf: Entering directory .' autoreconf: configure.ac: not using Gettext autoreconf: running: aclocal --force -I m4 autoreconf: configure.ac: tracing autoreconf: configure.ac: adding subdirectory extra to autoreconf autoreconf: Entering directoryextra' autoreconf: running: aclocal --force -I ../m4 autoreconf: configure.ac: adding subdirectory pix_artoolkit to autoreconf autoreconf: Entering directory pix_artoolkit' autoreconf: running: aclocal --force -I ../../m4 autoreconf: running: libtoolize --copy --force libtoolize: putting auxiliary files in.'. libtoolize: copying file ./ltmain.sh' libtoolize: putting macros in../../m4'. libtoolize: copying file ../../m4/libtool.m4' libtoolize: copying file../../m4/ltoptions.m4' libtoolize: copying file ../../m4/ltsugar.m4' libtoolize: copying file../../m4/ltversion.m4' libtoolize: copying file ../../m4/lt~obsolete.m4' libtoolize: Consider addingAC_CONFIG_MACRO_DIR([m4])' to configure.ac and libtoolize: rerunning libtoolize, to keep the correct libtool macros in-tree. autoreconf: running: /usr/bin/autoconf --force configure:15277: error: possibly undefined macro: AC_LIB_APPENDTOVAR If this token and others are legitimate, please use m4_pattern_allow.
