DSSI "path not found" after upgrade to Etch

[Nigel Henry <cave.dnb@tiscali.fr>]

I'd appreciate a bit of help to fix this problem.

I had DSSI plugins installed on Sarge from Willem Engen's repo, and they had 
been working ok, but since upgrading to Etch, the desktop launchers fail to 
work. Trying as user on the CLI with the same command, I got a DSSI "path not 
found", and the plugin obviously doesn't load.

The path was "jack-dssi-host whysynth.so" as an example, and if I changed it 
on the desktop launcher to the full path 
"jack-dssi-host /usr/lib/dssi/0.9/whysynth.so" whysynth starts ok, and same 
goes for the CLI.

I Googled DSSI_PATH , and a spanish blog suggested,
export DSSI_PATH=/usr/lib/dssi/0.9
followed by
echo $DSSI_PATH
which verified the path as /usr/lib/dssi/0.9

I can now load the dssi plugin on the CLI with "jack-dssi-host whysynth.so", 
but the same command on the desktop launcher still won't work.

The spanish blog also suggested adding to ~/.bashrc
export DSSI_PATH=/usr/lib/dssi/0.9
Which I did by adding it to the bottom of the file (I havn't messed 
with .bashrc before) , still no change from the destop launchers for the 
plugins. Logged out of KDE, then back in, but no change.

Now I'm stuck. 

Would ~/.bash_profile, which is also still at default status have any effect 
on the entry I made in ~/.bashrc?  I've put it below.

# the rest of this file is commented out.

# include .bashrc if it exists

#if [ -f ~/.bashrc ]; then
#    source ~/.bashrc
#fi

# set PATH so it includes user's private bin if it exists
#if [ -d ~/bin ] ; then
#    PATH=~/bin:"${PATH}"
#fi

# do the same with MANPATH
#if [ -d ~/man ]; then
#    MANPATH=~/man:"${MANPATH}"
#fi

Any help very much appreciated.
