How to depend on package in EGG?

[Ruslan Mahmatkhanov]

Good day!

I want add option in port's Makefile to depend on textproc/py-enchant.
But how i can do it? It installs as python egg.

.if defined(WITH_ENCHANT)
RUN_DEPENDS+=${LOCALBASE}/????/enchant/__init__.py:${PORTSDIR}/textproc/py-enchant
.endif

What should i wrote instead ???? in left part of this RUN_DEPENDS string?

Thanks in advance for answer.
