cPanel Advisory: IO::Compress and DNS Zones missing

The following advisory was just received from cPanel team:

Dear cPanel Partner,

The CPAN module IO::Compress::Zlib version 2.006 has caused several issues for
some. The problems arise due to a dependency upon IO::Compress::Base not
being correctly installed. This is due to some mirrors not being updated with
the proper dependency information. Since the dependencies are incorrect, the
module no longer functions properly. The most noticeable problem from this is
the complete breakage of DNSAdmin, however other issues are caused. To
alleviate the problems, cPanel is providing a hotfix which can be applied in
the following manner:

From the command line:

1. SSH into your server as root.
2. At the command line, execute the following:
/scripts/autorepair io_compress_gzip

Or from WHM:

1. Log into WHM as root
2. Enter the following URL into your browser's address bar:
https://__YOURSERVERHERE__:2087/autofixer
(example: https://www.example.com:2087/autofixer)
3. When prompted, enter: io_compress_gzip

The autofixer will report it is applying "IO::Compress::Zlib autorepair
verison 1.1" This process replaces the IO::Compress::Zlib with
version 2.005. Also a hold back has been enabled to prevent the perl installer
process from installing IO::Compress::Zlib version 2.006 until a new
version is available that fixes this problem.

For non-cPanel servers that experience this issue, it is also possible to
resolve this manually by performing the following steps:

1. SSH into your server as root.
2. Execute the following commands:
wget http://search.cpan.org/CPAN/authors/id/P/PM/PMQS/IO-Compress-Base-2.006.tar.gz
tar xfzv IO-Compress-Base-2.006.tar.gz
cd IO-Compress-Base-2.006
perl Makefile.PL
make
make install

The manual fix will also work for a cPanel server.

In order to expedite the process, we have also updated all published builds to include the fix.

If you incur any difficulties during the update process or have any questions
or concerns you wish us to address, please contact our support team by
opening a support ticket though the manage interface.

I finally bit the bullet and upgraded from 10 to "CURRENT" this weekend, hoping that these kinks had indeed been resolved, but I still got the dreaded IO::Compress email after it had completed and had to run through this autofix process. I think cPanel's lying ;)
