alternative dependencies, dependency record.

[Peter Danecek]

Hi all,

for one of my ports I would like to offer some flexible and I plan to allow different ports (here: PIL and Pillow) to satisfy the same dependency.

This is what relevant part from the Portfile:

    # PIL dependency: allow both PIL and Pillow to satisfy it.
    depends_run-append      path:${python.pkgd}/PIL:py${python.version}-Pillow


But I then realised that for the py27-Pillow port (and the same is true for py27-pil) no dependents are registered, while the port itself (here: py27-cartopy) still depends on it and I wonder if this is correct.

petr% sudo port -v dependents py27-pillow
py27-Pillow has no dependents.

petr% port installed py27-cartopy
