JHBuild failed to build GNOME Shell

I am almost there. Fixing error after error, walking baby steps, but
getting to know a little bit about the build process. This time, I am
stuck with GNOME Shell. Two things here:

- first is not the problem but I thought it would be worth mentioning:
a lot of warning about deprecated functions in the
clutter-animation.h, clutter-texture.h and cogl1-context.h. Is it
expected?

- Second, and the reason behind my failed build:
make[4]: *** No rule to make target `ShellMenu-0.1.typelib', needed by
`all-am'.  Stop.

Any ideas?

Thanks,
Luiz
