Original text:
The blas and lapack libraries provided by libatlas-base-dev are unaware of their dependency on gfortran,

>ldd /usr/lib/atlas/libblas.so /usr/lib/atlas/liblapack.so
/usr/lib/atlas/libblas.so:
 linux-gate.so.1 => (0xb7fca000)
 libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7b1c000)
 /lib/ld-linux.so.2 (0xb7fcb000)
/usr/lib/atlas/liblapack.so:
 linux-gate.so.1 => (0xb7fce000)
 libblas.so.3gf => /usr/lib/atlas/libblas.so.3gf (0xb754d000)
 libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb73fe000)
 /lib/ld-linux.so.2 (0xb7fcf000)

Linking to these libraries results in unresolved symbols if -lgfortran in not added. The affects Hardy and Intrepid.

In contrast under Debian Lenny, the libraries provided by libatlas-base-dev are aware of the dependency. Under Lenny,

Confirmed.
atlas fails to build from source on i386. See http://launchpadlibrarian.net/16970147/buildlog_ubuntu-intrepid-i386.atlas_3.6.0-21.5ubuntu1_FAILEDTOBUILD.txt.gz. Therefore you get the old 3.6.0-21.1ubuntu3 libatlas-base-dev version, which does not depend on libgfortran3.

On amd64 atlas was correctly build and on amd64 libatlas-base-dev correctly depends on libgfortran3. So when the FTBFS on i386 is fixed, the dependency issue will be solved.

[Albert Damen (albrt)]

Please sponsor the attached debdiff.

The merged package builds fine in an i386 pbuilder on i386.
Please note, it will not build in an i386 pbuilder on amd64, as atlas uses uname to detect the architecture, which detects the host arch instead of the chroot arch.
The required files can be found on MoM. On Dad the dsc and diff for 3.6.0-21.5 are missing.

The new package also solves the linking/dependency issue from the original bug report.

[Albert Damen (albrt)]

Attached is the debdiff between the old and new ubuntu versions.

[Cesare Tirabassi (norsetto)]

mok0 is already working on this, subscribing him.

[Launchpad Janitor (janitor)]

This bug was fixed in the package atlas - 3.6.0-22ubuntu1
