On the old computer, this command (one line):

fink list -ti | grep -v system- | grep -v virtual- | cut -f 2 | xargs echo

should get you a decent list of all the installed packages on the old 
system.

For trying to run old fink on new-system, edit the file /opt/sw/bin/fink 
at the top to change "/usr/bin/perl5.18" to whatever the perl version is 
on your system (I think /usr/bin/perl5.30). Then see if that lets you 
run. If it does, I recommend `fink rebuild fink` followed by `fink 
reinstall fink` if successful.

If you do need to start fully from scratch, you can move your old 
install on new-system to /opt/sw-original to save all your config files, 
then install fink anew in /opt/sw, and copy data files as needed.
