hwsensors-plugin on debian testing

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Greetings.

I'm using debian testing and installed libsensors3 and libsensors-dev.
Compiled and installed ok. But, when I run xfce4-panel, it gives-me the
folowing output.

** Message: xfce4-panel: module minicmd successfully loaded

** (xfce4-panel:19500): WARNING **: xfce4-panel: module
/usr/lib/xfce4/panel-plugins/libsensors.so cannot be opened
(/usr/lib/xfce4/panel-plugins/libsensors.so: undefined symbol:
control_class_set_unique)
** Message: xfce4-panel: module wavelan successfully loaded

I've added /usr/lib/xfce4/panel-plugins to ld.so.conf and run depmod -a.
And it still gives me the same message.
Can you help me tracing the problem?

Thanks.
