Compilation error rddtool

Hi,

I started from scratch my compilation and now I have an error about rrdtool. but everything is enable, here what I have;

  "kernel=6.6.83~4faf5e1f9f8ed30339cf7a310d7f5685-r1"
ERROR: unable to select packages:
  rrdtool (no such package):
    required by: luci-app-statistics-24.333.73113~0a6a2f1[rrdtool]
make[2]: *** [package/Makefile:99: package/install] Error 2

and here, in my config;

CONFIG_PACKAGE_luci-app-statistics=y
CONFIG_LUCI_NEW_RRDTOOL=y
# CONFIG_LUCI_OLD_RRDTOOL is not set

CONFIG_PACKAGE_collectd-mod-rrdtool=y

idea?
