There are two ways to do this in a package.

1. I can make an ifeffit-lite package and add that to the repository. 
This may take a bit of time and I am not sure how much use it will be as
most modern machines have enough memory for the current binaries.  In
addition as  Bruce points out the reduced memory alloctions will severely
limit the utility of the program.

2. You can "roll your own" package.  I am away from home and a fast
internet connection right now but I could post a short article on how to
do this on the wiki or elsewhere.  I hesitate to just put it in this email
because I might forget a step and waste your time when there is a problem.
