Your freetds.conf is not read by dbinit(); it's consulted when you
call dbopen().

Oof, what a little whitespace can do to the meaning of a message!
There is no msgno 2, which at first confused me.  But there is a msgno
20009: 

$ grep 20009 include/sybdb.h
#define SYBECONN        20009   /* Unable to connect socket -- SQL
                Server is unavailable or does not exist. */

So I think your error stems from dbopen(), not dbinit().  If you
install your error handler before calling dbopen() (as you should) you
can choose *not* to return INT_EXIT.  For more information, look for
the word "saith" in src/dblib/dblib.c.  

Try the same server with bsqldb or t0001.  These programs install an
error handler and print a more useful message, e.g.:

$ build/src/dblib/unittests/t0001 -S localhost
found localhost.FreeTDS for jkl in "../../../PWD"
About to logon as "jkl"
About to open "localhost"
DB-LIBRARY error (dberr 20009 (severity 9): "Unable to connect:
Adaptive Server is unavailable or does not exist"; oserr 61:
"Connection refused")

HTH.
