Attached.

I did the tests with 2 configs, apparently with the same symptom.

The first is arm-cortex_a8-linux-gnueabi with a few (supposedly
irrelevant) changes: prefix dir, number of parallel jobs and
tuple's alias.

The second has a few changes, most notably I set the kernel headers
version to 2.6.32 since they are closer to the kernel I'm using
(http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap-2.6.git
at 4fa42e4679).

Thanks for the links. Anyway I'm not doing dirty tricks as passing name[-1]
as gst-doc used to, so perhaps my problem is not the same.

Thanks,
