13 <para>Your host system should have the following software with the
14 minimum versions indicated. This should not be an issue for most
15 modern Linux distributions. Also note that many distributions will
16 place software headers into separate packages, often in the form of
17 <quote>&lt;package-name&gt;-devel</quote> or
18 <quote>&lt;package-name&gt;-dev</quote>. Be sure to install those if
19 your distribution provides them.</para>

70 interferes with building some LFS packages. To check this, look in
71 /usr/lib and possibly /usr/lib64 for libgmp.la, libmpfr.la, and
72 libmpc.la. Either all three should be present or absent, but not only
73 one or two. If the problem exists on your system, either rename or
74 delete the .la files or install the appropriate missing

96 <para>The reason for the kernel version requirement is that we specify

98 at the recommendation of the developers. It is also required by
99 udev.</para>
100
101 <para>If the host kernel is earlier than &min-kernel; you will need to replace
102 the kernel with a more up to date version. There are two ways
103 you can go about this. First, see if your Linux vendor provides a &min-kernel;
104 or later kernel package. If so, you may wish to install it. If your
105 vendor doesn't offer an acceptable kernel package, or you would prefer not to
106 install it, you can compile a kernel yourself. Instructions for
107 compiling the kernel and configuring the boot loader (assuming the host
108 uses GRUB) are located in <xref linkend="chapter-bootable"/>.</para>

148 point to other software (such as dash, mawk, etc.) may work, but are not
149 tested or supported by the LFS development team, and may require either
150 deviation from the instructions or additional patches to some
