My configuration was yet exactely same that what you propose, but the
line explicitsuite=true

All this procedure work as explained.

I then tried to test my new build environment, for that I downloaded
the squeeze source of the nano package, then I try to build it with
pdebuild-cross. First it failed because the apt database was not up to date.

I eventually found that I can use the ordinary pbuilder command with
the proper configuration

 sudo pbuilder update --configfile /etc/pdebuild-cross/pdebuild-cross.rc

Then I tried to pdebuild-cross nano, the script ran without error, and
produced ...
A package for amd64, the host architecture;

The log is at http://pastebin.ca/1887268

To summarize,
- the script execute the proper:
pdebuild --architecture mipsel --configfile
/etc/pdebuild-cross/pdebuild-cross.rc
- It updates local package dependencies
- then execute A00cross-deps-hook to update apt-cache for mipsel
- then use dpkg-buildpackage -us -uc  -rfakeroot without specifying
any architecture

I'm not able to sort out what happen, my knowledge of pbuilder is to shallow.

Can you understand it?

Thanks again for your help

Marc

PS: I will report the doc wishes, once I have better understood the
process, some rough edges (like the update problem) appears only when
practicing.
