Hi,

I’m trying to install mysql gem on ruby 1.9.1p129.

Here the result : (do in root)

gem1.9 install mysql – --with-mysql-config=/usr/bin/mysql\_config

So, it seems “version.h” is missing. I have install  
“libmysqlclient16-dev” because I’m using mysql 5.1.

I have found mysql\_version.h in package.

Did I miss another package ?
