:-) left guile-devel only this time

Yes. Just made things working both with guile-1.6 and guile-1.8 [on the same
machine I mean], by changing the module definition as this [if others would like to
do so...]:

;; --
(define-module (struct gtrees))

(let ((ef-ver (string->symbol (effective-version))))
  (case ef-ver
    ((#{1.6}#)
     (dynamic-call "init_gtrees_module"
		   (dynamic-link "/usr/local/lib/gtrees-0.3/libgtrees.so")))
    (else
     (dynamic-call "init_gtrees_module"
		   (dynamic-link "/usr/local/lib/gtrees-0.5/libgtrees.so")))
    ))

Well, as much as possible, due to the amount of work I have, I'll stick to debian
packages until I finish the application I am working on, then I'll try 2.0 and
guile-vm, I can't wait! but I have to :-(

If you remember, thanks to dsmith, on xchat, I could produce a guile-pg [debian]
package patched that works with guile-1.8 [the problem was a dependency one: here is
what I wrote to myself:

;;;
;;; Debian package [patching guile-pg-0.16]
;;;

A] Getting the source

	cd ~/alto/admin/guile-pg
	apt-get build-dep guile-pg
	apt-get source guile-pg
	cd guile-pg-0.16

B] Changing the dependency towards guile-1.8
   
 	cd guile-pg-0.16/debian
	
   perform the following change

<	Build-Depends: debhelper (>> 4.0), quilt, libpq-dev, guile-1.6-dev
>	Build-Depends: debhelper (>> 4.0), quilt, libpq-dev, guile-1.8-dev

	But I also wrote something about patching libpostgres.c and .h,
	[postgres-7.4: the only SW that's still is not a debian package [in my
	dependency 'little tower'] but a manual compilation [and they are @ 8.4 now,
	so quite late on this side too ...] can't find right now but if people are
	interested i'll make that info avalable too, let me know.

C] Then I changed the module definition [attached]

;; --

So I was wondering, in order to be as practicle as possible and save 'lost'
debugging time, is it possible to install both guile-gnom0 and guile-gnome2 on the
same machine ?

	I think I tried and didn't work, but I might be wrong.

That would fantastic because I could right away porting the development I am doing
and later on port the old apps.

Cheers,
David
