Hi, I had the same worries with FreeTDS 0.83, DBI 1.6 and Perl 5.10. To solve this problem, after making "Perl makefile.pl" for package DBD:Sybase 1.10, I edit the "makefile" file and add at the end of EXTRALIBS and LDLOADLIBS lines the <FreeTDS path>\lib\libct.dll.a library. Then i made the "dmake" command and "dmake install". This worked for me. Excuse me for my English.
