First off, run:
$ autoreconf -f -i

Then the usual $ ./configure # and $ make #

In order to build gss-proxy the following development packages are needed
additionally to a ISO C compiler:

    autoconf
    automake
    docbook-style-xsl
    doxygen
    findutils
    gettext-devel
    libini_config-devel
    keyutils-libs-devel
    krb5-devel
    libselinux-devel
    libtool
    libverto-devel
    libxml2
    libxslt
    m4
    make
    pkgconfig
    popt-devel

For testing via $ make tests # you additionally need these three
packages:

    krb5-server
    nss_wrapper
    socket_wrapper

NOTE:
The minimum supported Kerberos version is MIT Kerberos 1.11.2 as it includes
[1] and [2]
The keytab initiation feature where Gss-Proxy acquires crdentials on behalf
of clients using a ketab will only be available in MIT in 1.12
This patch [3] can be used to backport the feature in 1.11.2, this new feature
simply allows combining two [4][5] features introduced in MIT 1.11
