Missing package gee when building vala with jhbuild

Hi,

When I build vala with jhbuild, I get the following error:

I'm running Linux Mint 12. I've installed the libgee-dev package. It
installs /usr/share/vala/vapi/gee-1.0.vapi. If I make a symlink to this
file at /usr/share/vala/vapi/gee.vapi, I get these errors when building
vala instead:

Changing "Set" to "Gee.Set" at the two offending locations silences
those errors, however I get many more errors on the next build attempt,
so I think I'm barking up the wrong tree.

I've tried using the valac in my distribution's standard repositories
which is version 0.14, and a 0.18 build in the vala-team ppa. At least I
hope that is what I did: bug 673972 makes it difficult to check which
version is being used.

I had the following warning from configure:
> configure: WARNING: unrecognized options: --disable-gtk-doc

The non-comment lines in my jhbuildrc file are:
> checkoutroot = '~/programs/gnome/checkout'
> buildroot = '~/programs/gnome/build'
> prefix = '/opt/gnome/debug'

Any help getting the build to succeed would be appreciated.
