INDEX build failed

[Xavier]

Hello,

It surely depends on build option I use in the dependency chain for 
dbus, but I cannot figure which it is.

In short
----------------------------------------------------------------------
# rm -rf /usr/ports && mkdir ports
# cd /usr/ports
# svn co svn://svn.freebsd.org/ports/head .
# make index

Generating INDEX-9 - please wait..make_index: Circular dependency loop 
found: dbus-1.8.20 depends upon itself.
----------------------------------------------------------------------

It happens as well on 9-STABLE, 10.3-RELEASE, CURRENT

I can submit if needed my /var/db/ports/*/options files

Thxs
