Help in installing DBD::InterBase

Hi,
I've got problems in compiling DBD::InterBase: make test says:
PERL_DL_NONLAZY=1 /usr/local/perl5.6/bin/perl -Iblib/arch -Iblib/lib
 -I/usr/local/perl5.6//lib/5.6.0/i686-linux -I/usr/local/perl5.6//lib/5.6.0
 -e 'use Test::Harness qw(&runtests $verbose); $verbose=0; runtests @ARGV;' t/*.t
t/00base............install_driver(InterBase) failed:
  Can't load 'blib/arch/auto/DBD/InterBase/InterBase.so' for module DBD::InterBase:
  blib/arch/auto/DBD/InterBase/InterBase.so: undefined symbol: isc_dsql_execute at
  /usr/local/perl5.6//lib/5.6.0/i686-linux/DynaLoader.pm line 200.
 at (eval 1) line 3
Compilation failed in require at (eval 1) line 3.
Perhaps a required shared library or dll isn't installed where expected
 at t/00base.t line 38
dubious
        Test returned status 255 (wstat 65280, 0xff00)
DIED. FAILED tests 4-5
        Failed 2/5 tests, 60.00% okay
Of course I ran make before and set required variables.
My config: Debian Potato, InterBaseSS_LI 6.0.1, Perl 5.6, DBI 1.14, DBD::InterBase 0.21
