Ok.

I solved it.  
Had to recompile gem mysql

Didn’t come up that easy.

First I had to go to  
/opt/local/lib/ruby/gems/1.8/gems/mysql-2.7  
and run  
sudo ruby extconf.rb  
–with-mysql-config=/opt/local/lib/mysql5/bin/mysql\_config  
manually from there.

That made a proper Makefile

And only after that  
sudo gem install mysql  
started to work.
