24    <para os="m1">In multilib builds we install compilers and libraries for each available
25    architecture.  The description below says that perl installs several hundred
26    libraries, but they are used by invoking <command>perl</command>, not by linking
27    to them with <command>ld</command>.  Although it is possible to install perl for
28    32 bits, move it to a different name, and then install the 64-bit version, it is
29    almost always invoked as just <command>perl</command>. That means only the
30    libraries and modules for the last version installed will be accessible. We
31    therefore only install one version.</para>
32
33    <para os="p1">Perl does not, by default, know about library directories with names other
34    than lib, such as lib64.  The following patch will allow it to install to lib64.</para>

37
38    <para os="p3">There is a further (possibly cosmetic) anomaly - if we install perl and
39    then run <command>perl -V</command> it will claim that libc is in /lib.  The
40    following patch fixes this, but only takes effect when <command>make install
41    </command> is run.</para>
