 warning). How can I save the file in a different location?

 build system cannot be coerced to put the file where you want it, you can
 move it in a post-destroot block, or you can override the destroot phase
 entirely, like you did in the portfile you submitted in #47806.

 > Sounds like you want to modify the user's environment, outside of what
 happens in MacPorts? MacPorts cannot do that. The user has to do it on
 their own. The port can use the `notes` command to display text to the
 user advising them what they must do.

 I think this finally corrects my previous misinterpretation that Macports
 could edit my login profile (~/.profile), which contains lines such as the
 one below.  I now realize these lines must have been placed there when
 Macports itself was installed.  Based on what you're saying, Macports
 cannot edit login profiles.  Correct?
