Can't exec "libtoolize": No such file or directory at /usr/local/share/autoconf/Autom4te/FileUtils.pm line 345, <GEN3> line 6.
autoreconf: failed to run libtoolize: No such file or directory
autoreconf: libtoolize is needed because this package uses Libtool

Have you tried using glibtoolize to prepare lib packaging? I.e.

glibtoolize
autoreconf -i
./configure
make
make check

This should make sure libtool packaging info is created with GNU libtool.
