IIRC for glist-of, wct, and wcp handling it does need the generated SCM
wrappers. Can't recall quite right. Besides, it is completely wrong for
one incompatible version to overwrite another, leaving its pieces
around. This means e.g. the gnucash .deb couldn't install correctly.

Maybe to indicate more clearly that those files are separate from the
new ones, and that they are old. Reminds one of the links in $prefix/lib
as well, but that pulls in the whole versioned-modules problem because
we don't have a linker.

True, although it shouldn't be much work. In time we'll develop wrappers
for the old API, or better yet get patches into gnucash to have it use
the newer API.

Thanks. Sorry to be so demanding, but a smooth install is important ;)
