We've seen a couple reports of this sort of problem that were due to
trying to use a copy of Pg.so that was compiled against a different
version of Perl.  It seems the Perl guys have been changing the
binary-level interface for loadable modules recently :-(.

You may need to build the Perl module locally in order to get a copy
that works with the version of Perl you have.

yes, it seems to be something like You wrote above. I've been looking into 
File: DynaLoader.a
Dir: /usr/lib/perl5/5.00503/i386-linux/auto/DynaLoader

and have (using mc) seen this:
( --NOTICE-- the 3rd line, containing ""PL_markstack_ptr"" instead of above missing ""Perl_markstack_ptr"" )

DynaLoader.o:
00000000 d LastError

Any further ideas ?
