Building external modules

[Tommy Nordgren]

Where can I find printed docs on how to build external modules on MacOS 
X?
For some reasons perldoc don't work correctly when piping output into 
the lpr command.
All titles/subtitles get duplicated cchhaarraacctteerrss (like the 
previous word), making the output nearly unreadable.
Are there any suitable books on this topic?
