Out of curiosity, is there a reason to prefer Fink over MacPorts (which has Ifeffit and Demeter already available)?   I wouldn't say that MacPorts or wxPerl on MacPorts are perfect, but it does work for many of us.

As an aside, if you built ifeffit, building Larch should be much easier, assuming that the scientific python stack is available for Fink.  It's basically "python setup.py install".  Or, one can install Anaconda Python.
 

Also, Bruce and I have been working on getting to the point where Demeter uses Larch by default.   Some of this is at https://github.com/bruceravel/demeter/pull/40, and Athena with Larch is working for me on Mac OSX.    I think we have the basic functionality needed, and are at the testing and tweaking stage.

Making a MacPorts (and/or Fink?) installer for Larch looks like it would be pretty easy, and that could further simplify distribution for OSX.   That is, Anaconda Python is very good, but means that one has to install Demeter with MacPorts and also Larch from an Anaconda channel.  Using a single packaging system so that  "<something> install demeter"  installed Larch + Demeter would certainly be easier.  I think that we'd probably be better off choosing one of the "port Unix tools to OSX" systems. I don't have a strong opinion, and it's been awhile since I used Fink.  

Opinions on Fink vs MacPorts (or the others) would be helpful.

Thanks,
