When I want to build a package for the native architecture, I don't
need to be root. If there are missing build dependencies, then the
missing packages are listed, so that I can install them as root,
then I can retry the package build as a normal user. So, the only
things I do as root is to install packages. The build is entirely
done as a normal user.

Or perhaps I can try pbuilder-user-mode-linux.

The issue is that all this will require a major rewrite of my
scripts...

Apparently you need root to satisfy the build *dependencies* (which
means you need to be root to install a package--but we new that
already).

However 

 ...most packages do not need root privilege to build, or even
 refused to build when they are built as root. pbuilder can create a user
 which is only used inside pbuilder and use that user id when building,
 and use the fakeroot command when root privilege is required.

Anyhow, nothing is more convincing than success, and if your "lighter"
and less "mortal" method is successful, God bless and full speed ahead!

IMHO, this is overkill, at least in my case. And I don't like to
require root just to build a package.

Installing dpkg-cross just installs: cross-config dpkg-cross
libconfig-auto-perl libdebian-dpkgcross-perl. This is not
sufficient.

I'm much less so, but I've heard people recommending pbuilder for this (chroot).

 pbuilder --create --architecture i386
 pbuilder --build mypackage.dsc

etc...

It seems that you are missing the '386 (or more precisely the '686)
executables. Perhaps you need the package dpkg-cross.

I'll leave that question to someone more knowledgeable.
