libtoolize: You should add the contents of the following files to `aclocal.m4':
libtoolize:   `/usr/share/aclocal/libtool.m4'
libtoolize:   `/usr/share/aclocal/ltoptions.m4'
libtoolize:   `/usr/share/aclocal/ltversion.m4'
libtoolize:   `/usr/share/aclocal/ltsugar.m4'
libtoolize:   `/usr/share/aclocal/lt~obsolete.m4'
libtoolize: Remember to add `LT_INIT' to configure.in.
libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.in and
libtoolize: rerunning libtoolize, to keep the correct libtool macros in-tree.
libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am.
