FDB Client failing to start on macOS Catalina (v10.15.6)

Question

while trying to do a setup of local installation of janusgraph-fdb on my local MacBook. But after the setup as I started gremlin-server.sh, I am getting this issue. steps I followed:

1. Installed FoundationDB.pkg (v6.2.20) on macOS Catalina (v10.15.6) (both CLIENT and Server)
2. downloaded and unzipped Janusgraph-foundationdb-adapter (v0.1.0)
3. downloaded and unzipped Janusgraph (v0.3.2)
4. ran fdb adapter over janusgraph....

Janusgraph-foundationdb-adapter-dir/install.sh Janusgraph-dir

5. tried starting gremlin-server.sh... it is failing with the following error.

(This error is not coming in lower versions of macOS.)

2. Janusgraph-foundationdb-adapter (v0.1.0)
3. Janusgraph (v0.3.2)
4. macOS Catalina (v10.15.6)

Below mentioned steps worked for me :

1. Copy libfdb_c.dylib in your directory.
2. Set DYLD_LIBRARY_PATH=/usr/local/lib as Environment Variable.
