Runtime missing-symbol errors?

[walt <wa1ter@xxxxxxxxxxxxx>]

I'm trying to figure out why evolution-2.8 doesn't work on DF:

(evolution-2.8:39636): evolution-shell-WARNING **: Cannot activate
'OAFIID:GNOME_Evolution_Mail_Component:2.8': Can't find symbol
Bonobo_Plugin_info in
`/usr/pkg/lib/evolution/2.8/components/libevolution-mail.so'

Note that the error does not come from ld-elf.so trying to load
a stale library -- this message comes from evolution itself.
Does this imply the use of dlopen(), maybe?

And here is part B of the puzzle:

#nm /usr/pkg/lib/evolution/2.8/components/libevolution-mail.so |
grep Bonobo_Plugin

000aeb80 D Bonobo_Plugin_info

So the 'missing' symbol really is defined in the library, but it
can't be found for some reason.

Any ideas what is going wrong?
