+ <dd>
+ Sometimes changes to the LLVM source code alters how the build system
+ works. Changes in libtool, autoconf, or header file dependencies are
+ especially prone to this sort of problem.
+ <p>
+ The best thing to try is to remove the old files and re-build. In most
+ cases, this takes care of the problem. To do this, just type <tt>make
+ clean</tt> and then <tt>make</tt> in the directory that fails to build.
