Thanks Yves,
I just downloaded pidip from the http://ydegoyon.free.fr/pidip.html page and its fine - the file on the http://ydegoyon.free.fr/software.html seems to be corrupted - download ended after a couple of seconds on two machines i tried.
using tar xvfz pdp_pidip_osx.tar.gz i got this far
...gzip: stdin: unexpected end of file pdp_pidip_osx/include/pdp_comm.h pdp_pidip_osx/include/pdp_compat.h pdp_pidip_osx/include/pdp_config.h pdp_pidip_osx/include/pdp_config.h.in pdp_pidip_osx/include/pdp_control.h tar: Unexpected EOF in archive tar: Unexpected EOF in archive tar: Error is not recoverable: exiting now
now I'm getting this:
dyld: /usr/local/bin/pd can't open library: /usr/local/lib/libMagick-5.5.6-Q16.0.dylib (No such file or directory, errno = 2)
I have installed ImageMagick with fink - but this libMagick is nowhere to be found... on with the search!
Thanks, Rob
