pg_citus extension error

Hello, 

A postgresql database v14 is running in a jail.
I installed pg_citus with portupgrade: no error messages

I get an error, 
(1). when I create extension citus; or
(2). when I change shared_preload_libraries and restart the database

(1)
errormessage:
SQL Error [58P01]: ERROR: could not load library
"/usr/local/lib/postgresql/citus.so": /usr/local/lib/libcurl.so.4:
Undefined symbol
"nghttp2_option_set_no_rfc9113_leading_and_trailing_ws_validation"

(2)
when I set the value in postgresql.conf
shared_preload_libraries = 'citus'
and restart, then I get the error-message
service postgresql restart
