MASTER_SITE_BACKUP with ${MASTER_SITES:S/%SUBDIR%/${MASTER_SITE_SUBDIR}/}
at the end and MASTER_SITE_OVERRIDE ?= ${MASTER_SITE_BACKUP} are used
together in /etc/make.conf.
So, use simple workaround: replace ( and ) by their URL-encoded %-codes.
(There is the bug in that area still remains, but not fatal:
the combination above don't understand properly ending :tags sometimes
and tries mass fetching with ending :tags unstripped.
Someone should look at that whole bsd.ports.mk/bsd.sites.mk mess)
While I am here, slightly rearrange ending :tags.
This is the FreeBSD Ports Collection. For an easy to use
WEB-based interface to it, please see:
http://www.FreeBSD.org/ports
For general information on the Ports Collection, please see the
FreeBSD Handbook ports section which is available from:
http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/ports.html
for the latest official version
or:
The ports(7) manual page (man ports).
These will explain how to use ports and packages.
If you would like to search for a port, you can do so easily by
saying (in /usr/ports):
make search name="<name>"
or:
make search key="<keyword>"
which will generate a list of all ports matching <name> or <keyword>.
make search also supports wildcards, such as:
make search name="gtk*"
For information about contributing to FreeBSD ports, please see the Porter's
Handbook, available at:
http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/porters-handbook/
NOTE: This tree will GROW significantly in size during normal usage!
The distribution tar files can and do accumulate in /usr/ports/distfiles,
and the individual ports will also use up lots of space in their work
subdirectories unless you remember to "make clean" after you're done
building a given port. /usr/ports/distfiles can also be periodically
cleaned without ill-effect.
