I don't know about that, but the other thing is that pre- and post-  
blocks can be defined multiple times. They don't override one another.  
So if the portgroup defines a pre-configure phase, and the portfile  
defines a pre-configure phase, MacPorts would happily call both of them.

Perhaps muniversal could do this in a post-extract phase. That way,  
you could write a (single) pre-configure phase, and in it, you would  
loop over the list of requested architectures and do your reinplacing  
in each one.

I haven't used fortran. Does fortran not offer something equivalent to  
C's preprocessor directives?
