| 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="p3">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> |

| 38 | <para os="p5">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 |
