umh, something tells me this is not enough: hooks are run as root, while
the build is not, so the build user would not be able to write there.
Currently the build username or user ID is not exported to the hooks, so
the better you can do is to chmod 777 TMPDIR and TMP (programs using
/tmp should be able to use that securely anyway...)

the directory where the package is kept and the build is done is
hardcoded to /tmp/buildd/ till 0.216, where it was made configurable and
moved to /build/.

JOOI, can you try with pbuilder from backports and see whether with the
changed build place something different happen?

yes, because you're building as root, which can write anywhere he likes
:)
