24 <title>Installation of Perl</title>

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

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