Fink is similar to macports, it is a package manager for installing various applications for OSX. TCHPC currently maintains an rsync mirror (for internal TCD use) of the finkinfo files. Please refer to the fink project page for information on how to obtain and install fink. The address of the rsync mirror is

rsync://thammuz.tchpc.tcd.ie/finkinfo/

You should have at least something similar to this in your /sw/etc/fink.conf file

Mirror-rsync: rsync://thammuz.tchpc.tcd.ie/finkinfo/
ProxyFTP: http://username:password@proxyA.tcd.ie:8080
