[PD] Bizzare problem with freeverb~

there's no gui setup and it tries to grab the soundcard too quickly and
failes, at least that's my understanding of the problem.  I noticed this
using -nogui mode and -rt, -alsa in Linux.

I don't think the problem in my case is startup latency, since when I run pd
-nogui I can still hear audio (therefore pd does connect to the soundcard),
but I don't hear the audio with the reverb that freeverb~ is suppose to add.
Did not work for me. I've tried different delay times and same thing
happens: freeverb~ does not apply any effect on the audio when I run pd

This looks like a bigger problem to me, maybe related to running Pd from the
command line on Mac OS X (see
http://www.mail-archive.com/pd-list@iem.at/msg27281.html). I believe this
since I also tried running the patch from the command line WITHOUT the
-nogui flag, and the delayed loadbang doesn't start the dsp at all!!! So
maybe it's a bug to be fixed.

Any ideas?
