the lfs build process is similar for every package build, starting from within the sources directory.
0. cd /sources
1. tar -xvf package-version.tar.bz2
2. cd package-version
3. Follow the lfs book commands from HERE, ALWAYS!
Some packages MUST be built outside the package directory, therefore the command ..
mkdir -v ../package-build
Most packages are built from within the package-version directory so you would still be there...
4. Now ./configure..., make..., make install or whatever the commands are in the book
5. cd .. back to sources
6. rm -r package-version and if necessary rm -r package-build.
7. done ;-)
Always remove the old package directories to keep the process clean. Keep the tar-balls as they may be needed again
The commands listed in the book are only for steps 3 and 4. The book avoids repetition of the basic steps as this is described in preceding text and those familiar with the process only wish to focus on the important commands.
Once you understand the steps the book will make sense and you can then have fun!
