===> Installing dependencies for evolution-data-server-3.35.1nb13
==========================================================================
The following variables will affect the build process of this package,
evolution-data-server-3.35.1nb13.  Their current value is shown below:

        * KRB5_DEFAULT = heimdal
        * SSLBASE = /usr
        * SSLCERTBUNDLE (not defined)
        * 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 the value
of variables in the first group before continuing.  Be sure to run
`/usr/bin/make clean' after the changes.
