Connecting to mysql database using MAMP

[Pierre Del.]

Hi,
I have downloaded MAMP (local server for Mac, with Apache, Mysql and  
PHP). It works fine on port 8889. But when I try to connect Rev to it  
using       get revOpenDataBase("MySQL", "localhost:8889",  
"MyDataBase", "root", "root"), I always get the error message :  
Unknown MySQL server host 'localhost:8889' . Am I using a bad syntax?  
Or is there some kind of incompatibility?

Thanks for your help
