Many of the installation commands involve scripts which have ${PREFIX} hard coded into them.  ${PREFIX} is often hard coded when trhe package is created by the port.  In my opinion, the options "-p" and "-P" should be removed from pkg_add.

You are correct, this needs to be done on a port by port basis.  In some 
ports this is going to be a big job, because in some cases the 
"/usr/local" is hard coded into certain binaries.

For example, suppose the C source code contains something like:
char applications_dir = "/usr/local/share/applications";
and this is filled in by the ./configure script.

How is that handled?
