Connection problem DBD::ODBC, unixODBC to remote ADABAS-D

I am experiencing an annoying problem getting an DBD::ODBC connection
(via unixODBC) working from a client machine A (Suse linux) to a an 
ADABAS-D-11 database running on a remote machine (B, also Suse linux)


-------------------------- Machine A (client)
   Linux  2.6.8-2
   Perl            : 5.008005    (i586-linux-thread-multi)
   OS              : linux       (2.6.8.1)
   DBI             : 1.43
   DBD::Proxy      : install_driver(Proxy) failed: Can't locate 
RPC/PlClient.pm in @INC
   DBD::ODBC       : 1.06
----------------------------------------------


Connections using isql (unixODBC) from machine A to machine B run
smoothly, hence I reckon, unixodbc and prima facie 
odbc-misconfigurations are not the problem.


When I try to do a trivial connect (below) with DBD::ODBC to the very 
same DSN that I could connect to using isql without a problem, I get a
segmentation fault.


----------trivial-connect----------------------
#!/usr/bin/perl
use DBI;
my $dbh = DBI->connect('dbi:ODBC:emanuel-sbart', '***','***') ||
                 die "can't connect to $data_source: $DBI::errstr";
$rc = $dbh->disconnect;
exit();
--------------------------------

and inspection of the sql.log (of unixodbc, full below) reveals the 
error message:

---------------------
Message Text = [[unixODBC][Driver Manager]Data source name not found, 
and no default driver specified]
[ODBC][13206][SQLError.c][424]
-------------------------------


Can anybody give me an idea which direction could be pursued to solve
this problem ?

What beats me is that isql can connect to my remote database, but an
dbd::odbc connection to the same DSN utterly fails.

Any hints welcome.
