Try using the enclosed patch. It changes the configure script not
configure.in as I don't have the demanded version of autoconf. But it should
work. If your Openssl is installed in a non-standard place you will perhaps 
need to hint with something similar:
CPPFLAGS=-I/software/openssl-0.9.6/include \
LDFLAGS=-L/software/openssl-0.9.6/lib ../configure --enable-kaserver
--disable-shared --with-openssl=/software/openssl-0.9.6 \
--with-krb4=/software/krb4-1.1
