[e6423a01] | 24 | <para os="m1">In multilib builds we install compilers and libraries for each available |
---|
[bf8c11f] | 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] | 39 | then run <command>perl -V</command> it will claim that libc is in /lib. The |
