Hi all,  
I am having issues with installing the mysql gem with the mysql  
version 5.0.81 .Bulk updating Gem source index for:  
[http://gems.rubyforge.org](http://gems.rubyforge.org)  
Building native extensions. This could take a while…  
ERROR: Error installing mysql:  
ERROR: Failed to build gem native extension.

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby  
extconf.rb install mysql – --with-mysql-dir=/usr/local/mysql  
–with-mysql-lib=/usr/local/mysql/lib  
–with-mysql-include=/usr/local/mysql/include  
can’t find header files for ruby.

Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/mysql-2.7  
for inspection.  
Results logged to /Library/Ruby/Gems/1.8/gems/mysql-2.7/gem\_make.out

I just tried googing and also referred a lots of blogs but nothing seems  
to be working.

Anbody please shed some light on this issue of mine

You need to pass something when you install mysql gem. Just google for  
it.
