If they'd accept that, that would be great.

I'm not sure I understand.  If we're doing our homework, then you
should be able to install several versions of guile at the same time
with no problems.  Some apps will link against libguile6 and some
against libguile9.  I've been trying to make sure that's true in
Debian, at least, and I think we've been doing fairly well.

Alternately, we might want to consider versioning the guile-internal
lib directory.  i.e. put libsrfiX, etc. into /usr/lib/guile/1.6.1 for
example, and modify our internal LTDL_LIBRARY_PATH appropriately.

Since these libs aren't public, there may be no point to having them
in /usr/lib and dealing with the complexity of careful libtool

Anyone?  I'd be happy to arrange for this immediately if we think it's
a better approach.

I'm still trying to track down some problems, but it's getting better.

Yep, maintaining a separate build/install tree for combinations of
guile, g-wrap, and guppi for building various test trees of gnucash is
somewhat a PITA :>
