Hello, I am on Mac OSX and I have been using the terminal for a couple of months now as it is the only way to get pd to work. At the beginning I had some difficulties to install it and I have simply downloaded the package version of pd+tk of Adma Lindsay which installed everything for me. Now, I have a bit more knowledge of terminal commands and as I have downloaded some externals from pure-data.org, I wanted to try again to install them myself. I get stuck to the particular commands where I have to type make clean then make and finally make install. My terminal tells me 'command not found'. In any hope of discovering something by myself, I noticed the Makefile file in some external' s directories and try to type ./Makefile then I got the answer Permission denied(as superuser). I understand that has more to do with OSX/Unix language and less with pd itself, however I am sure many of you can help to answer my newbie questions. Also any reference website to learn a bit more about the command line will be most appreciated. Thanks a lot
