[exim] dlopen problems

Hi

i've been using a dlopen extension for long time, but now i one
server i get the following error:

failed to expand ACL string
"${dlfunc{/usr/local/exim/exim-ext.so}{ip2country}{$sender_host_address}}":
dlopen "/usr/local/exim/exim-ext.so" failed:
/usr/local/exim/exim-ext.so: undefined symbol: message_id

it works on a similar server with same exim & gcc version (exim
is 4.80.1 self compiled), looks like local_scan variables are not
visible to the extension, nut why ? anyone had the same problem
or has a solution for this ?

Thanx & best regards ...
