47 <para>This package and the next two (Expect and DejaGNU) are
48 installed to support running the test suites for binutils and GCC and other
49 packages. Installing three packages for testing purposes may seem
50 excessive, but it is very reassuring, if not essential, to know that the
51 most important tools are working properly.</para>

53<!-- <para>Note that the Tcl package used here is a minimal version needed

106 <para>The various <quote>sed</quote> instructions after the
107 <quote>make</quote> command removes references to the build directory from
108 the configuration files and replaces them with the install directory.
109 This is not mandatory for the remainder of LFS, but may be needed in case a
110 package built later uses Tcl.</para>
111
112 <para>To test the results, issue:</para>

115
116 <note>
117 <para>
118 In the test results there are several places associated with clock.test
119 that indicate a failure, but the summary at the end indicates no
120 failures. clock.test passes on a complete LFS system.
