portsdb fails for 6-CURRENT

[Charlie Root]

the Makefiles for textproc/xalan-c and www/mod_auth_useragent appear
to reference ${DOCSDIR} w/o defining it or including anything that 
defines it.

********************************************************************
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not supported with partial or out-of-date ports collections -- in
particular, if you are using cvsup, you must cvsup the "ports-all"
collection, and have no "refuse" files.)  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 WITH/WITHOUT settings).

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