   If you run ldd on the full path to the binary, it should give the 
path to the library; was it /lib/libgcc_s.so.1 ? That is a library 
provided from FreeBSD's base system. My little understanding of it 
mentions it had to do with trying to get things working when migrating 
form gcc to clang as can be learned at 
https://wiki.freebsd.org/Ports/libgcc_linking_problem .
   I do not know of a good way to track library connections across 
dependencies. Perhaps a poudriere build with a jail just for this from 
scratch or at least forcing all dependencies to rebuild at the same time 
may help get a more thorough searchable log set or moving this library 
out of the way temporarily to watch such a build for its failures that 
result. I'd be interested in how to better understand library linking 
and loading but I'm not there yet.
