[PD] fluid~ : add_history unresolved?

[Larry Troxler]

Hi, does anyone know where  add_history is defined? When I create a fluid~, 
this is what happens:

/usr/lib/pd/extra/fluid~.pd_linux: /usr/lib/pd/extra/fluid~.pd_linux: 
undefined
symbol: add_history
 fluid~
... couldn't create

Thanks!

Larry
