Warning, although our project is now approaching general usability for
developers, it is still a work in progress and may contain inaccuracies
or omissions.  Be sure to read the APSL and the GPL, so that you will know your
rights.  Send any email regarding this document to proclus@iname.com.  Please 
remember that we are in alpha, so this procedure is for the adventurous.  Almost
all the packages work, but there are still many problems.  Join the project,
if you want them fixed.

Once again, the Makefiles and sources may be in somewhat rough shape. 
Darwin has been in a state of flux, and we often have to respond to that 
at the code level.  This especially applies to the major projects like 
the package manager and the stuff at gnu-darwin.com.  Here are the files 
you will need if you want to build the package manager.

http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/gnu-darwin/pkg_install/
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/gnu-darwin/fetch/
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/gnu-darwin/libfetch/
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/gnu-darwin/libftpio/
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/gnu-darwin/libc/

We will probably eliminate libftpio down the road.  You should already 
have libmd.

Here are some skeletal instructions for building the package manager. 
Check the porting tips, if you run into problems.  After that, please 
feel free to contact me if you have any questions about it.

cd libftpio/
make                              # you can probably ignore the errors
cp *.h /usr/local/include/

ranlib /usr/local/lib//libftpio*
cd ../fetch/
cp *.h /usr/local/include/        # no need to make fetch
cd libfetch/
make                              # you can probably ignore the errors

Recently, I have been having trouble with the following error.

/usr/bin/ld: Undefined symbols:
__divdi3

You can shim it out in
pkg_install/info/show.c as follows.

_divdi3(){return(-1);}

Alternatively, you can have a look at libc/*/divdi3.c and try to figure 
out how to make it work. I tested the shimmed version of pkg_info on
/var/db/pkg/gnomeutils-1.2.1/ and it seems to work, but I have not 
tested it with the ports system yet.

Finally, it should be noted that there is currently a problem with
pkg_add because none of the available versions of tar recognize the
--fast-read flag.  Although this problem was not present in the pkg_add
binary that was distributed with TDC, it is present in the sources.  
As an intermim measure, This flag should be deleted from the sources
or simply edited from the resulting binary by overstriking with spaces.
