MySQL Gem Error

I just can’t seem to get the mysql gem installed on my Mac OSX Leopard. (Disclaimer: I had this problem from the original Ruby-version in Leopard). I downloaded the 1.9.1 and installed on Mac OSX as mentioned by Dan Benjamin in http://hivelogic.com. I installed Mysql version from source/package etc., But no luck in getting the mysql gem installed. Here is the error I get:

a-mac:$ sudo gem install mysql — —with-mysql-dir=/usr/local/mysql
Building native extensions. This could take a while…
ERROR: Error installing mysql:

Gem files will remain installed in /usr/local/lib/ruby/gems/1.9.1/gems/mysql-2.7 for inspection.
Results logged to /usr/local/lib/ruby/gems/1.9.1/gems/mysql-2.7/gem_make.out

I have the exact same issue.
Can’t find the solution.
I tried this too:
sudo gem install mysql — —with-mysql-config=“/usr/local/mysql/bin/mysql_config”

I also have the same issue. The only work around is install mysql-ruby 2.8.1 from source. Run the ‘extconf.rb’ > ‘make’ > ‘make install’. I still prefer the ruby-gem way and hope it’ll be fixed soon.
