#56016: make test uses the installed version of MacPorts, not the just-built one
------------------------+--------------------

 Priority:  Normal      |  Milestone:
Component:  base        |    Version:  2.4.99
 Keywords:              |       Port:
------------------------+--------------------
 `make test` uses some combination of the already installed MacPorts and
 the just-built one. This can cause tests to fail if the installed version
 doesn't have the same capabilities as the built version.

 For example, when I had MacPorts 2.4.2 installed, and then cloned master
 and ran `./configure` and `make` and `make test` (without running `sudo
 make install`), the "Sed in place" test failed, saying it `can't read
 "portutil::autoconf::sed_ext_flag": no such variable`.
 `portutil::autoconf::sed_ext_flag` was removed in
 [209e78f57a3886d1091948c17948fcd4928c855c/macports-base] and no remnant of
 it remains in master, so it must have gotten that from the installed copy
 of MacPorts 2.4.2.
