unorthodox build setup?

[Mark Brethen]

I only need to set it during build and destroot. How about setting the variable in the pre-build and pre-destroot phases?

But you don't know for certain that the configure phase will run in this invocation of the port command. The user might run "sudo port extract yourport" (which in your example will set configure.dir) and then later run "sudo port configure yourport" (and configure.dir will be back to its default value). So don't set options in one phase and expect them to be available in another phase.
