[PD] gridflow issues

[yvan volochine]

hi,

trying to debug a patch using gridflow-0.12 on pd-extended-0.42.5 
(ubuntu-lucid), I have some issues:

- some tcl errors at pd startup[1]:

(tcl) invalid command name ".xb6cde8.c"
while executing ".xb6cde8.c delete gf08c44168"

and then (30 or more):

.x8e3b590 no such object

- then I tried to build gridflow-0.13 but it does not find half of the 
headers and I have a couple of gcc errors just with ./configure
(libs not found are libdc1394, libmpeg3, quicktime, ... although they 
are all installed and can all be found in /usr/include)

as updating the OS is not currently an option, I wonder if there is 
something obvious I'm missing...

sorry for not posting the complete backtrace but this happened on 
another machine than mine

ps: ruby-1.8.7 and gcc/g++-4.4.3
pps: gridflow-0.12 was installed from a *.deb

any help is appreciated
cheers,
_y

[1] those errors go away if I remove gridflow/abstractions from the pd-path
