basically, go to the ./pd/ directory and type scons

permission denied ... are you sure, that you have set the permissions
correctly?

well, i think this was a clash when using both the fftw and the threaded
soundfiler ... i probably won't rewrite the threaded soundfiler for 0.39
... i rewrote it for 0.38 and would probably have to rewrite it for
0.40-1.00 ... and since there will be an array external working for
xsample, vasp, py, that _will_ be threaded, why will pd need features of
a professional software?

fftw: replacing mayerfft algorithm with fftw algorithms, between 5 and
10 times faster for an fft
icc: compile pd with the intel c compiler (not recommended)
atomic operations: some atomic operations for stack counting ...
implemented to make threaded messaging threadsafe.
lockfree: use the lockfree fifo implementation (improvement for thread
synchronisation)
gathreadlocks: i removed them, since they are horribly broken due to
miller's changes between 0.38 and 0.39
cheers ... tim
