   4 <para>Warning: do NOT run <userinput>make uninstall</userinput> on this
   5 package if you apply the <emphasis>sed</emphasis> fix to change the
   6 <filename class="directory">libexec</filename> directory definition. The
   7 <emphasis>uninstall</emphasis> rule in the <filename>Makefile</filename>
   8 file runs a command like <userinput>rm -rf
   9 &lt;libexecdir&gt;/*</userinput> Since we change the <filename
  10 class="directory">libexec</filename> directory to <filename
  11 class="directory">/usr/bin</filename> it'll run <userinput>rm -rf

  14 <para>When installing Gawk using glibc-2.1.x on your base system,
  15 it may be necessary to use a fix to prevent a variable name conflict. The
  16 following commands can be used in this case.  Note that these commands
  17 can also be used for other glibc versions so if you aren't sure, then
  18 use the first version.</para>
