[PD] 0.38.4 devel: glitchy sound / load_object: Symbol "" not found

[patrick]

hi,

i'm trying to be on the edge...

cvs -z3 -d:pserver:anonymous at cvs.sourceforge.net:/cvsroot/pure-data co 
-r devel_0_38 pd

./bootstrap.sh
cd src
autoconf
./configure --enable-jack --enable-threadedsf --enable-gathreadlocks
--enable-setuid
../bin/pd

Pd version 0.38.4 devel {OSS 2} {ALSA 1} {jack 5} courier

i'm using a .pdrc in my root folder to load external and set dir. first, 
i do a Test Audio and Midi: a can hear the tone, but it's noisy and 
glitchy. in the console i got:

load_object: Symbol "plugin_tilde_setup" not found
plugin~: can't load library
load_object: Symbol "OSC_setup" not found
OSC: can't load library
load_object: Symbol "zexy_setup" not found
zexy: can't load library
...
...

note that 0.38.2 work fine.
thanks for any input!
pat
