I get the following error :  perl: symbol lookup error: /usr/bin/perl5/DBI/1.607/exec/5.10/lib/perl5/auto/DBI/DBI.so: undefined symbol: Perl_Istack_sp_ptr But I can connect perfectly with the below:  /efs/dist/fsf/freetds/0.82/exec/bin/tsql -S DBName -I $HOME/freetds.conf -U userName -P passwOrd what might be the issue?
