I have followed the above instructions. if i run : cpan > install DBD::Oracle i get the message, DBD::Oracle is up to date. does that mean my installation is flawless? Because i'm not able to run a program. I get the following error on running a program: ------------------------------------------------------------------------------------------------- install_driver(Oracle) failed: Can't load '/usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi/auto/DBD/Oracle/Oracle.so' for module DBD::Oracle: /home/ralf/oracle/instantclient_10_2/lib/libclntsh.so.10.1: symbol semtimedop, version GLIBC_2.3.3 not defined in file libc.so.6 with link time reference at /usr/lib/perl5/5.8.0/i386-linux-thread-multi/DynaLoader.pm line 229. at (eval 1) line 3 Compilation failed in require at (eval 1) line 3.
