When running ./autogen.sh for menu-cache i'm receiving some warnings:

$ ./autogen.sh 
+ [ x != x ]
+ aclocal
configure.in:15: warning: macro `AM_PROG_LIBTOOL' not found in library
+ autoheader --force
+ AUTOMAKE=automake libtoolize -c --automake --force
./autogen.sh: 1: libtoolize: not found
+ automake --add-missing --copy --include-deps
libmenu-cache/Makefile.am:10: Libtool library used but `LIBTOOL' is undefined
libmenu-cache/Makefile.am:10:   The usual way to define `LIBTOOL' is to add `AC_PROG_LIBTOOL'
libmenu-cache/Makefile.am:10:   to `configure.in' and run `aclocal' and `autoconf' again.
libmenu-cache/Makefile.am:10:   If `AC_PROG_LIBTOOL' is in `configure.in', make sure
libmenu-cache/Makefile.am:10:   its definition is in aclocal's search path.
+ autoconf
configure.in:15: error: possibly undefined macro: AM_PROG_LIBTOOL
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
+ rm -rf autom4te.cache

Just saying in case someone may be interested.
