Did you build 0.3.7 from source?  I thought there was a 0.4.0 release that's
in at least a couple of distributions.  I see my up-to-date Gentoo box only
has 0.2.1.

Our dependency policy is outlined in $toplevel/README.dependencies, but it's
roughly: only library versions that have been released (in major
distributions) for at least 6 months.


Looking at my 0.2.1 install:

> #include <goffice/utils/datetime.h>

Present.

> #include <goffice/utils/go-glib-extras.h>

Present.

> #include <goffice/utils/go-locale.h>

Not present.

> #include <goffice/utils/go-format.h>

Present.

Of course, the particular API is more relevant.

Our general method of handling stuff like this is to keep it as intact as
possible, and copy the sources into lib/«whatever»/.  The hope would be it's
more fully factored out (say into goffice), and we can migrate to using the
real version rather than our copy.

I suggest looking at:

- src/gnome/gnc-plugin-basic-commands.c, which is similar, being the core
  "plugin" for the basic commands/menu items.

- src/import-export/ofx/gnc-plugin-ofx.c, which is even more similar, as it's
  basically the same thing. :)

Note that most plugins will register themselves with the plugin manager,
which means they need to be called during application init.  In the case of
the core plugins (basic-commands, account-tree, &c.) that's straightforward:
just call it from the startup code.  I the case of optional modules
(OFX/HBCI, &c.), the module init function needs to make the call.  I'm not
sure that there's a compelling case to make a CSV importer optional, but it's
good to be somewhat isolated, regardless.
