Firstly, it sounds like the portaudio package you installed is horribly 
broken, as the symbolic links should be created at package install time. 
As for where the symbolic links should point to, here is what I have on 
my system.

luke at linden:/usr/lib$ ls libportaudio.* -l
- -rw-r--r-- 1 root root 26844 2005-10-25 21:03 libportaudio.a
- -rw-r--r-- 1 root root   849 2005-10-25 21:03 libportaudio.la
lrwxrwxrwx 1 root root    22 2006-04-10 17:07 libportaudio.so -> 
libportaudio.so.0.0.18
lrwxrwxrwx 1 root root    22 2006-03-29 08:27 libportaudio.so.0 -> 
libportaudio.so.0.0.18
- -rw-r--r-- 1 root root 22764 2005-10-25 21:03 libportaudio.so.0.0.18

You can see that both symbolic links point to libportaudio.so.0.0.18. 
Just about all shared libraries installed on a Linux system have similar 
symbolic links, to allow program to be able to find libraries, even if 
libraries have received minor upgrades, say libportaudio.so.0.0.20. 
Thats how I understand it anyway.

As for the undefined symbol, I would strongly suggest you check what 
version of portaudio you have. I would also symbolically link as shown 
above, and re-compile the package just to be safe. I think version 18.1 
at least is required.

Hope this helps.
