Fetching precompiled packages for external install

I'm not sure if I've given a reply, so this might be a double post. :-)

Exactly. If I would have wanted that, my choice would be the tradidtional
way to use portinstall with its -p option, similar to "make package"
from a port's directory.

That sounds complicated...



But many thanks for your ideas, I found a way to achieve my goad.
As you will see, the solution is VERY ugly, but it seems to work.
It's a simple script that first downloads the requested package,
then the dependencies it needs are filtered out of the -v messages
of pkg_add. Afterwards, the script is called recursively on these
packages, to do exactly the same as with the requested package.

Here it is:



#!/bin/sh
#
# getpkg.sh 2008-08-19
#
# fetch a precompiled package as well as it dependencies
# for further installation

if [ "$1" = "" ]; then
	echo "$0 <package>"
	exit 1
fi
echo -n "fetching $1 ... "
if [ -f $1.tbz ]; then
	echo "$1.tbz already there"
	exit 1
fi
pkg_add -fKnrv $1 > $1.txt 2>&1
echo "done"
for DEP in `cat $1.txt | grep $1 | grep "depends on" | cut -d "'" -f 6 | cut -d "/" -f 2`; do
	echo "dependency for $1 is ${DEP}"
	$0 ${DEP}
done
rm $1.txt
exit 0



One problem that might occur: Do the depencency packages need to
include version numbering? The downloaded packages do not have
a version in their name. I will check if it works, or if the
versions need to be in the package file name.
