Kannel Installtion error CentOS 7

Dear Users,

I am getting the below error while trying to install Kannel after running
the command  make -j3 install :

-lxml2 -lz -lm -ldl -lpcreposix -lpcre -lcrypto -lssl -Wl,-rpath
-Wl,/usr/local/lib
smscconn.o: In function `smscconn_create':
/opt/knl/installs/kannel.svn/trunk/gw/smscconn.c:360: *undefined reference
to `smsc_soap_parlayx_create'*
collect2: error: ld returned 1 exit status
make[2]: *** [bearerbox] Error 1
make[2]: *** Waiting for unfinished jobs....
make[2]: Leaving directory `/opt/knl/installs/kannel.svn/trunk/gw'
make[1]: *** [install-recursive] Error 1
make[1]: Leaving directory `/opt/knl/installs/kannel.svn/trunk'
make: *** [install] Error 2

These are the steps I have followed so far :

   1. Install Postgres
   2. yum install postgresql-devel
   3. yum update
   4. yum groupinstall -y 'Development Tools'
   5. yum install libxml2-devel -y
   6. yum install openssl-devel -y
   7. Install GSOAP support

wget https://sourceforge.net/projects/gsoap2/files/latest/download
unzip download
cd gsoap/
./configure --prefix=/usr
make
make install

cd /opt/knl/installs/kannel/trunk/
./bootstrap.sh
./configure  --with-pgsql --enable-ssl --with-gsoap
--enable-start-stop-daemon --enable-pcre
make -j3 install

Then the above error occurs:

/opt/knl/installs/kannel.svn/trunk/gw/smscconn.c:360: *undefined reference
to `smsc_soap_parlayx_create'*


Please assist
