oh, I almost forgot something fairly important… my mercurial I installed in my home directory still works, and X11 apps I installed via fink (like gnucash and gnumeric) still work in Snow Leopard without having to recompile them. I suspect as long as the binaries you have were compiled with an x86 target at all, it will probably still run without recompiling, just in 32-bit mode.

I’m running Mac OS X version 10.5 (leopard), and I’ve install xcode 3.1. I need gnumeric and gnucash, which I use to track my finances. The current stable rsync version of fink contains gnumeric 1.8.1-3 and gnucash 2.2.5-52, both of which are close enough to the versions I have in Ubuntu Hardy Heron and Intrepid Ibex to be useable. gnumeric and its dependencies compiled and installed fine. the gnucash2 package, however, failed building some dependent library.
