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 mpfr-4.2.1-1-$(uname -m).pkg.tar.xz \
   /srv/pacman/repos/LFS/
repo-add /srv/pacman/repos/LFS/LFS.db.tar.xz \
         /srv/pacman/repos/LFS/mpfr-4.2.1-1-$(uname -m).pkg.tar.xz

Update the local cache and install the Mpfr package:

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

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

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