|

| 24 | <para>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
|
|---|
| [a1a7bae] | 31 | therefore only install one version.</para>
|
|---|
| [bf8c11f] | 32 |
|
|---|
| 33 | <para>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>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>
