Python packages installs .egg-info metadata directories when
--single-version-externally managed is specified, as the Python ports
framework does currently for all ports when USE_PYDISTUTILS is defined.
In this case the py-numpy port does *not* currently define
PYDISTUTILS_AUTOPLIST nor INSTALLS_EGGINFO, which precludes the contents of
the add-plist-egginfo: target from being executed.
This results in an .egg-info metadata directory being built, and staged, but
not installed.
Correctly specify INSTALLS_EGGINFO to compensate.
Additionally add an "Open" Goal Wiki entry [1] to look at automatically detecting the
presence of .egg-info metadata directories, since all ports leveraging
USE_PYDISTUTILS also use the --record mechanism for generating installed
file lists, and potentially deprecating INSTALLS_EGGINFO and related variables.
