Wow! Congratulations! You're the first person who is asking about
autobuilder here. The rest of community seems not interested in it (no
idea why).

A bit of explanations why this happened:
When autobuilder starts the build it uses so called minimal rootstrap
with the minimal list of packages like gcc, libc and similar. The rest
of packages required for the build should be mentioned in package's
control/Build-Depends* field[s].

So, your package should build-depend on -dev packages, which provide
libraries/includes to be able to use them. Only in this case they will
be brought to the system and can be used in the build.

In your case you can identify missing build-dependencies by looking
at .pc files with the same names as modules mentioned in your configure
output. Something like this:

[sbox-chinook-armel: ~] > dpkg -S hildon-1.pc hildon-fm-2.pc
hildon-help.pc
libhildon1-dev: /usr/lib/pkgconfig/hildon-1.pc
libhildonfm2-dev: /usr/lib/pkgconfig/hildon-fm-2.pc
libhildonhelp-dev: /usr/lib/pkgconfig/hildon-help.pc

So, you should add libhildon1-dev, libhildonfm2-dev
and libhildonhelp-dev to your package's Build-depends: and try again :)

Thank you for using autobuilder. 
Don't hesitate to ask more questions if any.
