bug in apt-cross?

[Wookey <wookey@wookware.org>]

I've been messing with the emdebian toolchain builds in order to get
them in-sync and installable for testing as well as unstable.

The scripts are now in pretty good order thaks to Zumbi's sterling
work but if you build a set of tools in a testing chroot then you get
the wrong glibc, and all the tools built against that glibc
(currently 2.6.1-1 in testing, 2.7-3 in unstable).

If you do:
apt-cross -v -v -a arm -S testing -m http://ftp.uk.debian.org/debian -f -b libc6

then we get:
Filename: libc6_2.7-2_arm.deb
Download: (nothing to do)                 ]

Should apt-cross have gone and got the testing version, as asked?

And why is it failing to get and make a cross-package from the version
it has picked?

/etc/apt/sources.list only lists lenny, and
.dpkg-cross/sources.testing also only lists testing sources, but
apt-cross -a arm -u still gets a load of stuff from unstable.

Similarly for gcc-4.2. it chooses gcc-4.2.2-4 instead of -3. Although
in this case it does make some cross-packages.

apt-cross is v0.5.1

These tests done inside /jails/amd64-testing/ chroot

Am I missing something, or is it broken?
