akonadi port needs an update!!! WAS Re: Strange mix of mysql versions during qt4-mac install

[Nicolas Pavillon]

Hello, 

I just took maintainership of akonadi, so I did not yet take the time to look much at the port.

I will look into this, in particular since mariadb for instance is also explicitly referenced as a viable substitute for mysql. 

>> $ port contents mysql55 | grep mysqld
>> …
>> /opt/macports-test/lib/mysql55/bin/mysqld

The variants to be made should also take care of the paths problems, especially since they appear to change depending on the version:

$ port contents mysql5 | grep mysqld

  /opt/local/libexec/mysqld
(among other things). 
Akonadi is anyway presently announced as depending on mysql5. So mysql55 should have no links with this issue. 

>> In port akonadi one finds
>> ---
>> depends_run-append  path:libexec/mysqld:mysql5-server
>> configure.args-append  -DDATABASE_BACKEND=MYSQL

Finally, by looking at it, I realised these instructions are outdated. As for now, the port builds for sqlite anyway because of misconfiguration. The port will need rewrite anyway. 

Cheers, 

Nicolas
