Error while SQLBOX running with MSSQL support

Hi All,
I am trying to implement kannel cvs version and sqlbox cvs version with
mssql support.

I have installed freeTDS successfully.

configure kannel successfully with below command
./configure --with-mssql=/usr/local --enable-localtime

the make and make installed

kanne runs successfully with MSSQL connectivity.

Then I configure sqlbox

./configure --with-kannel-dir=/home/kannel --with-mssql=/usr/local

and success fully configured
