Hi Martin,
If you are interested in trying to add improvements and fixes to FontForge, 
the first thing you need to do is see if you are able to build and compile 
FontForge on your computer, otherwise it will be difficult to test your fixes 
and improvements.

I am unfamiliar with the MAC, but understand there is homebrew as a method 
of install. This appeared to show at the top of the list (using homebrew):

lion-homebrew

If you are using Linux, you will need to load some developer utilities, 
such as gcc before trying to build it. If you are using a Debian based 
distro, such as Ubuntu, Mint, or others, this may help:
https://fontforge.github.io/en-US/downloads/gnulinux/
...likewise, for RPM based distros such as Fedora, RedHat, SuSE, Mageia, 
etc.

Pick-up the latest FontForge source:
https://github.com/fontforge/fontforge

Assuming you successfully compiled the program, installed it, and tried 
running it, the next thing you want to try, is tweak a few files and try 
compile and install again. Easiest way to do this is add some printf("I'm 
here\n); sort of lines in a file of interest...you could see an example of 
this in gutils/unicodelibinfo.c where you'l see some commented fprintf() in 
various locations.

...this is a follow-up from user-list:
