Installation problem with fresh Python 2.7 RPM from "Computational"

[andreas.motl@…]

Hey there,

first things first: Thanks for your work! We recently required Python 2.7 on RHEL6/CentOS6 and - voilà - found out you provide it in your "Computational" repositories.

However, we discovered there had been new releases of python27-2.7.3-6.2.sdl6.{1,2} on March, 11. A few days ago everything went fine installing python27-2.7.3-6.2.puias6 from your repositories after attaching to http://springdale.math.ias.edu/data/puias/$releasever/$basearch/os/Computational.

The distribution i'm verifying this on, is:

$ cat /etc/redhat-release
CentOS release 6.3 (Final)

With the fresh Python packages we receive:

Error: Package: python27-libs-2.7.3-6.2.sdl6.2.x86_64 (puias-computational)
           Requires: libz.so.1(ZLIB_1.2.0)(64bit)

It appears zlib 1.2.3 is installed:

$ yum info zlib.x86_64 | grep Version
Version     : 1.2.3

We also checked "Red Hat Enterprise Linux Server release 6.3 (Santiago)": Same zlib version (1.2.3).

Do you know why Computational's new Python 2.7 package is linked against zlib 1.2.0?

FYI: It's not a showstopper at all, we can either install python27-2.7.3-6.2.puias6 manually or explicitly attach to http://springdale.math.ias.edu/data/puias/computational/6.3/x86_64/ instead. Just wanted to get in touch and inform you about the problem in case this would break something more serious (indeed it prevents package upgrades when using baseline $releasever=6, this would receive the fresh Python packages linked against zlib 1.2.0 and croak).

To be more specific, the new Python packages appear in:

• ​http://puias.princeton.edu/data/puias/6/x86_64/os/Computational/
• ​http://puias.princeton.edu/data/puias/6.4/x86_64/os/Computational/

However, even RHEL6/CentOS6 release 6.4 would have zlib 1.2.3 installed, imho.

Cheers,
Andreas.
