Hi

When I do a “rake db:migrate”, I get the following error:

* * *

(in /Users/sneigaard/work/rails/mailtimer)  
dyld: lazy symbol binding failed: Symbol not found: \_mysql\_init  
Referenced from: /Library/Ruby/Gems/1.8/gems/mysql-2.8.1/lib/  
mysql\_api.bundle  
Expected in: flat namespace

dyld: Symbol not found: \_mysql\_init  
Referenced from: /Library/Ruby/Gems/1.8/gems/mysql-2.8.1/lib/  
mysql\_api.bundle  
Expected in: flat namespace

## Trace/BPT trap

If I log in to mysql and do a show variables like “%version%”;, I get  
his:

* * *

## protocol\_version = 10 version = 5.1.32 version\_comment = Source distribution version\_compile\_machine = i386 version\_compile\_os = apple-darwin9.6.0

I am runing OS X 10.6.4 64 bit

Any ideas what is wrong?

Thank you
