error installing MLT on debian

Hi and sorry for not exhaustively searching for threads..

I'm with debian squeeze 64bit, attempting to follow the kdenlive user-manual, I get the following result with the make -j3 command installing mlt:

/home/dav/mlt/src/modules/avformat/filter_avcolour_space.c:147: undefined reference to `img_convert'
producer_avformat.o: In function `convert_image':

make[1]: *** [all] Error 1
make[1]: Leaving directory `/home/dav/mlt/src/modules'
make: *** [all] Error 1

(that's just the end part)

can someone help? thanks

any one have some tips with installing kdenlive on debian stable???

edit: i was a little cautious about upgrading to sid so soon which is advised on the user-manual debian page... is that about the only hope I have of getting kdenlive and MLT?
