Fink

Libconfig has been accepted by Fink.

I've submitted libconfig to Fink:
https://sourceforge.net/tracker/?func=detail&aid=2795326&group_id=17203&atid=414256

If you want to test it before it makes to the distribution, please drop me
a line.

If you already know how to compile this program on OS X, have you
considered writing the Fink package yourself? Better to put your
expertise to work instead of waiting for someone else to reinvent
your wheel. There is information on writing packages in the
Documentation section of the Fink website

http://finkproject.org/doc

The Packaging Manual provides fairly comprehensive information of
the package description file and various packaging policies. The
Packaging Tutorial is a quick overview of how to create a packge
description file, and walks through the process for an actual
package. If you need help, visit the fink-devel mailing list or ask your
questions on the #fink irc channel.
