Rejoice, you're almost there :-)

So the plugin is loaded, it now tries to start the VM with image file. 
After you tried to load a project in the browser, did the .npsqueak 
directory in your home get created? If yes, then the npsqueak.so plugin 
succesfully executed the npsqueakrun script in 
/usr/lib/squeak/<version>. If not, make sure that file exists (you 
might want to look into the npsqueak.so binary for which script it 
actually tries to execute using

	strings npsqueak.so | grep npsqueakrun

The script creates some directories in $HOME/.npsqueak and copies the 
plugin image file from /usr/lib/squeak. After that, it executes the 
regular Squeak VM with the image copy, but redirects the main window 
into the browser page.

You might try a newer VM (3.7b-5 from http://squeak.hpl.hp.com/unix/) 
and the current image 
(http://squeakland.org/installers/SqueakPlugin.image.zip, extract that 
into ~/.npsqueak/).

I'm cc'ing Jens Lincke who is currently updating the Squeakland Linux 
packages (the download at squeakland is rather dated). We fixed a few 
oddities and might even have some shiny new debs for you :-) Also cc'ed 
is Ian so he knows what's going on.
