ive modules, you
will need to have a C compiler on your PATH where you run <code class="mendoza-code">jpm build</code>. For
POSIX systems, the compiler is <code class="mendoza-code">cc</code>.

<p>If you make changes to the source code after building once, <code class="mendoza-code">jpm</code> will try
to only rebuild what is needed on a rebuild. If this fails for any reason, you
can delete the entire build directory with <code class="mendoza-code">jpm clean</code> to reset things.
