You need to provide more context from the build log. Look for the 
command that actually failed and what the missing symbols are. "ld: 
symbol not found" is just the generic output that declares the type of 
error, but doesn't give any details as to who or why.

Also, there is no good upgrade path to 10.15 from earlier systems since 
Apple forced us to move away from /sw to /opt/sw. You can capture the 
list of previously installed packages on 10.11 and then ask the 10.15 
Fink to install those packages. See the top news item (2019-10-27) here 
<http://www.finkproject.org/news/index.php?phpLang=en> for the 
instructions to do that.
