Before to try to do it myself, and with the idea to share info on this matter, may I ask if any of you guys already attempted to modify/compile the guile-pg debian package [currently testing: 0.16-4+b1] with guile-1.8 ?
I am not (I work on pkgsrc not debian), but guile-pg currently depends on the 'load shlib as module' interface present in 1.4 and 1.6 but that was removed in 1.8. So I expect that it needs a new .scm that dynlinks the .so and exports all the right symbols.
