No, php5 will use whatever version of mysql5 is active. The message  
should really say "Unable to uninstall mysql5 because the following  
ports depend on it" (in other words, it shouldn't really list a  
specific version, since ports don't (can't) depend on specific  
versions of other ports). It's just trying to warn you that something  
installed depends on mysql5, so you should not uninstall (all  
versions of) mysql5. Since you already have a newer version  
installed, there's no problem.

No, the way you did it is fine.

All you have to do to uninstall the old mysql5 is to force the  
uninstall:

sudo port -f uninstall mysql5 @5.0.37_0+darwin_8+server
