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.. )
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
