********************************************************************
Before reporting this error, verify that you are running a supported
version of FreeBSD (see http://www.FreeBSD.org/ports/) and that you
have a complete and up-to-date ports collection.  (INDEX builds are
not supported with partial or out-of-date ports collections.
If that is the case, then
report the failure to ports at FreeBSD.org together with relevant
details of your ports configuration (including FreeBSD version,
your architecture, your environment, and your /etc/make.conf
settings, especially compiler flags and OPTIONS_SET/UNSET settings).

Note: the latest pre-generated version of INDEX may be fetched
automatically with "make fetchindex".
