# in case mysql was installed through fink, one should

sudo gem install mysql -- \
  --with-mysql-dir=/sw/bin/mysql \
  --with-mysql-include=/sw/include/mysql \
  --with-mysql-lib=/sw/lib/mysql \
  --with-mysql-config=/sw/bin/mysql_config

# if installed from source with make install :

sudo gem install mysql -- 
  --with-mysql-dir=/usr/local/mysql
  --with-mysql-include=/usr/local/mysql/include/
  --with-mysql-lib=/usr/local/mysql/lib/
  --with-mysql-config=/usr/local/mysql/bin/mysql_config

When installing mysql and mysql-dev with fink, gem is unable to find the mysql headers and libraries: you should specify their location. If compiled manually from source, gem will find it if /usr/local/mysql (or what ever other location you specified at compilation time) is in your path.

Install mySQL gem on a fink (vs self made) mySQL installation
