I do not see anything that could cause the version to be displayed differently.
Next idea would be to search for differences in config files, or the command lines used for starting the mysql server, but to be honest, I do not have a clue where to best start searching.

One thing I didn't mention is that these machines are managed by chef, and they do install the latest apt available mysql. We use Opscode's standard mysql recipe. I don't know if this affect something.

I started looking at a the command lines used for starting the mysql server and I did found there were some differences from the file in the deb package. Still I don't know if they justify the change in the version name.

I did overlook the documentation http://dev.mysql.com/doc/refman/5.1/en/information-functions.html#function_version that directs to http://dev.mysql.com/doc/refman/5.1/en/server-system-variables.html#sysvar_version for details.

It clearly states that "-log indicates that one or more of the general log, slow query log, or binary log are enabled. ". I haven't noticed that before, but the solution to my question was there...
