Finally I could solve the mess in my dev environment by reverting the MySQL folder to its original version (before upgrade) so I run Leopard but no upgrade of MySQL yet … present versions (all 32-bits as I cannot start kernel 64… ) Rails 2.3.4 Ruby 1.8.7 MySQL-5.0.67 (libmysqlclient.1.5.dylib…) gem mysql (2.7) if I upgrade to MySQL-5.1.38 , I believe I have to modify my client … I should I proceed ? thanks for your advice erwin ---

Why not just install mac ports and use the mysql-devel port ? ---

in all this mess, some posts also advise not to use ports… maybe the best move is NOT to move until Apple clarify it… MacBook w 64-bit architecture but EFI-32 should be allowed to boot w 64 kernel… some day (no technical reason to block it… but who knows the reason On 10 sep, 05:10, heimdull [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) wrote: > Why not just install mac ports and use the mysql-devel port ? > found a good URL w utility to test all that stuff… not an Apple one ---

Upgrading to SL is very easy and even gives you back quite a lot of HD space.However a few things have changed in the OS and you need to understand what is going on so you won’t get...

Ruby that comes with snow leopard is 64bit, so just get 64bit version of MySQL and compile mysql gem for the 64bit arch. ## Regards, Rimantas [http://rimantas.com/](http://rimantas.com/) ---

The key thing is whether the version of mysql you install is the same architecture as the version of ruby you currently have. Fred
