Prepare the build directory for the pacman user and build the package:

chown -R root:pacman .
chmod 2775 .
chmod 664 PKGBUILD
su pacman -c 'makepkg -L --nodeps'

Add the newly created package to the central package repository:

cp libtool-2.5.4-1-$(uname -m).pkg.tar.xz \
   /srv/pacman/repos/LFS/
repo-add /srv/pacman/repos/LFS/LFS.db.tar.xz \
         /srv/pacman/repos/LFS/libtool-2.5.4-1-$(uname -m).pkg.tar.xz

Update the local cache and install the Libtool package:

pacman -Syu
pacman -S libtool --overwrite \* -dd --noconfirm

Finally, copy the source files into the source repository and clean up the build directory:

mkdir /srv/pacman/source/LFS/libtool
cp PKGBUILD /srv/pacman/source/LFS/libtool
cd /sources
rm -rf libtool
