Had the same problem yesterday. I could not find the 0.80 version and 
tried to install another version of pd. But today i found out that it is 
not really great if you have to install all those externals yourself. So 
i tried again :-)

On tip i got yesterday: just make symbolic links. I hope you are a bit 
used to a linux system? Just type

                    locate libjack

and it will show you where to find the installed library. Then you make 
a symbolic link to it.

                    ln -s <real_name> <the_name_pd_looks_for>

so like
   
                   ln -s /usr/lib/jack.0.so.0 /usr/lib/jack.0.so.80      
(something like that)

In my case, pd started after this but still gave an error complaining 
about an unknown API (audio I/O stuck) but i think that has another 
cause. If you do have this problem, try to use pd -oss for now.
If pd starts, it will complain about other missing libraries. Just 
locate them and make symbolic links like above.
Everytime you start pd again, it will complain about another missing 
library, but in the end you'll get there. (depending on which libraries 
you'll load. Try without first.

If locate does not find a library wit the same name, you'll probably 
have to install it, using apt-get or yum or whatever ubuntu uses. But I 
only needed to do that when loadling some externals, not for the 
standard pd.

Please let me know if this helps. Maybe it is time to make a new 
installation guide for pd, because there seem to be some complexities 
for newcomers. (I have used pd on windows until know, and am quite 
familiar with linux, but i took quite some time to figure it all out.)
