==========================================================================
The following variables will affect the build process of this package,
htdavlock-0.2.  Their current value is shown below:

        * KRB5_DEFAULT = heimdal
        * SSLBASE = /usr
        * SSLCERTS = /etc/openssl/certs
        * SSLDIR = /etc/openssl
        * SSLKEYS = /etc/openssl/private

Based on these variables, the following variables have been set:

        * KRB5BASE (defined, but empty)
        * KRB5_TYPE = heimdal

You may want to abort the process now with CTRL-C and change their value
before continuing.  Be sure to run `/usr/bin/make clean' after
the changes.
