I'm totally new in pure data world etc. so pleeease be patient.
In order to start using pd a friend of mine suggested me not to use pd-extended but pd-vanilla, because it is still a working progress by Miller Puckette, while the last release of pd-exteded is quite old.
So I downloaded Pd version 0.46-4, 64 bits, compiled for Macintosh OSX 10.8 or later (because my computer is running OSX 10.9.5), but it doesn't even open. A very small empty window and a console window stucked at 1%.
Once I tried to install version 0.46-1 and it perfectly worked.
I also tried to compile Pd from source, but again I couldn't: following the instructions on this page (http://msp.ucsd.edu/Pd_documentation/x3.htm#s1.3), when I ran ./configure the terminal responded: -bash: ./configure: No such file or directory. Maybe because I can't figure out if I have TCL/TK installed (even though I red on the web that on mac OS 10.6+ it should be installed by default).
Any idea, explanation, suggestion?
I hope that all these informations are helpful enough.
