connecting to MSSQL 2005

I'm having a difficult time connecting to a mssql 2005 server.

solaris 10u5 sparc
freetds-0.82, hacked*
DBD::Sybase 1.09
perl 5.8.8
DBI 1.607
Microsoft SQL Server 2005 - 9.00.3042.00 (Intel X86)
  Developer Edition on Windows NT 5.2 (Build 3790: Service Pack 2)


*hacked = I had to modify cspublic.h for DBD::Sybase to compile.  I'm only 
assuming it was the right thing to do:

With this setup, I can connect to a mssql 2000 server.  But when I try to 
connect to a mssql 2005 server, i get an error:
DBI connect('server=server;database=db1','user',...) failed: OpenClient 
message: LAYER = (0) ORIGIN = (0) SEVERITY = (78) NUMBER = (41)
Server server, database
Message String: Unable to connect: Adaptive Server is unavailable or does 
not exist
  at tc.pl line 13


i tried using a different tdsver, but that didnt seem to work, and doesnt 
make sense anyway, since i can connect to mssql 2000.

any clues what I should look at?
