The short answer is: you can't.

On some systems you can probably use `libffi' to provide a wrapping.

However, since Gnome is free software, you can probably lobby to get
it changed to be more friendly.  For instance, you could have a new
interface added which implements the same functionality in a more
wrapper-friendly way.  This will benefit every language binding
implementor.

Does your wrapper use the `.defs' files that are in the gnome-guile
module?  That would be my preferred approach, if possible.  My reason
is that any improvements to the .defs file would benefit other
implementors.
