have to statically link <application>ZSH</application> against

<para>Linking <application>ZSH</application> dynamically against
<application>PCRE</application> and/or <application>GDBM</application>
produces runtime dependencies on <filename class='libraryfile'>
libpcre.so</filename> and/or <filename class='libraryfile'>libgdbm.so
</filename>respectively, which both reside in
<filename class='directory'>/usr</filename> hierarchy. If
<filename class='directory'>/usr</filename> is a separate mount point
and <application>ZSH</application> needs to be available in boot time,
then its supporting libraries should be in
<filename class='directory'>/lib</filename> too. You can move the
libraries as follows:</para>
<screen role="root"><userinput>mv -v /usr/lib/libpcre.so.* /lib/ &amp;&amp;
ln -v -sf ../../lib/libpcre.so.0 /usr/lib/libpcre.so</userinput></screen>
<screen role="root"><userinput>mv -v /usr/lib/libpcre.so.* /lib &amp;&amp;
ln -v -sf ../../lib/libpcre.so.0 /usr/lib/libpcre.so
<para><parameter>--disable-gdbm</parameter>: This parameter disables the
use of the <application>GDBM</application> library. Note: This is only
necessary if you use multiple partitions as <application>GDBM</application>
resides in <filename class='directory'>/usr</filename> and
<command>zsh</command> will be installed to <filename class='directory'>/bin
</filename></para>
mv -v /usr/lib/libgdbm.so.* /lib &amp;&amp;
ln -v -sf ../../lib/libgdbm.so.3 /usr/lib/libgdbm.so</userinput>

<para>Alternatively you can statically link <application>ZSH</application>
against <application>PCRE</application> and <application>GDBM</application>
if you modify the <filename>config.modules</filename> file (you need first
to run configure to generate it).</para>
