It was my chroot, after all [Was: Unstable vs testing: Atlas/blas problem -- ld.so patch dropped?]

[Dirk Eddelbuettel <edd@debian.org>]

Case closed, thanks to excellent help from Phil Blundell via the
#debian-glibc channel.  

It turned out that my chroot had an errant libblas.so -- unattributed to any
package -- which rm'ed after having purge'ed blas and blas-dev:

CHROOT chibud:/# dpkg --force-depends --purge blas blas-dev
dpkg: blas-dev: dependency problems, but removing anyway as you request:
 r-base-dev depends on blas-dev (>= 1.0-9).
(Reading database ... 38198 files and directories currently installed.)
Removing blas-dev ...
Removing blas ...
CHROOT chibud:/# ls -lL /usr/lib/libblas*
-rw-r--r--    1 root     root      2754540 Jun 20 18:43 /usr/lib/libblas2.so
CHROOT chibud:/# dpkg -S  /usr/lib/libblas2.so
dpkg: /usr/lib/libblas2.so not found.
CHROOT chibud:/# rm  /usr/lib/libblas2.so

I just rebuilt Friday's snapshot of R, and all is well now as it should be:

Package: r-base-core
Version: 1.8.0.cvs.20031114-2
Section: math
Priority: optional
Architecture: i386
Depends: perl, zlib-bin, atlas2-base | blas | blas2, [...]

Camm: I also learned from the glibc maintainers that BenC's patch is
apparently integrated upstream now which would be good news.

Thanks, Dirk
