#
# So ... if none of --prefix, --sysconfdir or --localstatedir are
# specified, set things up that way. If --prefix is given, use
# it for sysconfdir and localstatedir the way configure normally
# would. To change the prefix for everything but leave named.conf
# in /etc or named.pid in /var/run, then do this the usual configure way:
# ./configure --prefix=/somewhere --sysconfdir=/etc
# ./configure --prefix=/somewhere --localstatedir=/var
#
# To put named.conf and named.pid in /usr/local with everything else,
# set the prefix explicitly to /usr/local even though that's the default:

# XXXDCL This probably doesn't work right on all systems.

#
# Essentially the problems here relate to two different
# areas. The first area is building with either KTH
# or MIT Kerberos, particularly when both are present on
# the machine. The other is static versus dynamic linking.
#
# On the KTH vs MIT issue, Both have libkrb5 that can mess
# up the works if one implementation ends up trying to
# use the other's krb. This is unfortunately a situation
# that very easily arises.
#
# Dynamic linking when the dependency information is built
# into MIT's libgssapi_krb5 or KTH's libgssapi magically makes
# all such problems go away, but when that setup is not
# present, because either the dynamic libraries lack
# dependencies or static linking is being done, then the
# problems start to show up.
