Depends on the port, the problem and the availability of the  
maintainer :)
I am the maintainer of ocaml, but I don't have Leopard and I have  
been vaguely inactive lately, especially when the following lines  
were added to ocaml Portfile:

platform darwin 9 {
     macosx_deployment_target 10.4

This is what breaks on your system. Judging from the Changelog, this  
command hasn't been released yet, and this is why it breaks. I guess  
you can either:
- get the latest development version of MacPorts (or the 1.6 RC, if  
it includes this command)
- replace it with something that should work on the previous release  
of MacPorts, such as:

I'm Ccing Kevin who might have a clue.
