Comment 3 for bug 886423

Thanks, Clint and Hans.

This was the "best server" I had selected in Synaptic, and it's apparently outdated now:

$ sudo apt-cache policy php5-mysql
php5-mysql:
  Installed: (none)
  Candidate: 5.3.6-11ubuntu1
  Version table:
     5.3.6-11ubuntu1 0
        500 http://mirrors.ccs.neu.edu/ubuntu/ oneiric/main amd64 Packages

Today the "best server" search yielded the following, which fixed my problem:

$ sudo apt-cache policy php5-mysql
php5-mysql:
  Installed: (none)
  Candidate: 5.3.6-13ubuntu3.2
  Version table:
