Mac OS 10.6 Server can't install mysql gem - mysql

Question

I have nearly the same problem with the one discussed on the link below:
Error installing Mysql2 gem- 10.6 Server
I have followed the solution described but I get this:
sudo env ARCHFLAGS="-arch x86_64" gem install mysql2 -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
Building native extensions. This could take a while...
ERROR: Error installing mysql2:

mysql.h is missing. please check your installation of mysql and try again.

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.

Additionally I also tried to specified all mysql path:
sudo env ARCHFLAGS="-arch x86_64" gem install mysql --
--with-mysql-dir=/usr/local/mysql
--with-mysql-lib=/usr/local/mysql/lib
--with-mysql-include=/usr/local/mysql/include
--with-mysql-config=/usr/local/mysql/bin/mysql_config
And still get the error
$ sudo env ARCHFLAGS="-arch x86_64" gem install mysql2 -- --with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib --with-mysql-include=/usr/local/mysql/include --with-mysql-config=/usr/local/mysql/bin/mysql_config

Any help apreciated.

Answer 1

Do you have the mysql header files actually installed in the paths you link to? Have you installed a package of mysql that includes the header file?
/usr/local/mysql
I have installed mysql with ports and I have it in /opt
$ find /opt -name mysql.h
/opt/local/include/mysql5/mysql/mysql.h
you could try
$ find /usr/local -name mysql.h

Answer 2

I backtracked to version 5.1.59 of mysql instead of 5.5 and it worked fine.
It seems the gem is still incompatible with MySQL 5.5.xx
