Greetings!
Today I wanted to start learning pd, and I'm having a huge problem installing it (started at 8pm now it's 2:43 am)...
First the ubuntu ppa didn't work. This is the output from "sudo apt-get update"
W: Failed to fetch http://apt.puredata.info/releases/dists/luna/main/source/Sources 404 Not Found
W: Failed to fetch http://apt.puredata.info/releases/dists/luna/main/binary-amd64/Packages 404 Not Found
W: Failed to fetch http://apt.puredata.info/releases/dists/luna/main/binary-i386/Packages 404 Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.
so I have to compile it... 
I downloaded pd-extended,
cd to packages/linux_make and sudo make install
But the installation just won't go trough... I already successfully installed many dependencies (also everything mentioned here: http://puredata.info/docs/developer/Debian) but this I cannot find:
...

How many more of them are there?? And one more question... why am I having such a bad time compiling this? I don't find any people having this issues on the forums and on google...
