Having trouble building Upstart 1.6.1 from source

[Chris Angelico]

Hi! My apologies if this is the wrong place for this, but I can't find
an Upstart users mailing list, only the -devel.

I'm trying to install a recent Upstart into a Debian Squeeze box
(using a VM for testing at the moment). The build is failing, and I'm
not sure what I've done wrong. It's a mostly default Debian 6.0.6
except that the kernel has been built fresh from source, the latest
version thereof (3.7.2).

Based on the recommendation in:
https://lists.ubuntu.com/archives/upstart-devel/2012-December/002106.html
I took from source control, autoreconf'd, and tried to build; no difference.

The configure script completes with no visible complaints, but then make says:

rosuav at sikordebbie:~/upstart-1.6.1$ make
make  all-recursive
make[1]: Entering directory `/home/rosuav/upstart-1.6.1'

make[1]: *** [all-recursive] Error 1

Presumably there's a build step that I've missed. I'm using
json-c-0.10 built from source (and installed), and all configure
options at their defaults. I'm somewhat stuck here; is Upstart 1.6.1
incompatible with kernel 3.7.2? Have I mucked up kernel parameters?
Messed up the build incantation?
