For those who want/need to install a Perl app or extension without perturbing the
default perl library tree.
Possible reasons:
1. Disambiguating the existing libs from your libs (for testing perhaps)
2. Not wanting to or not having rights to login as a supervisor (or as a user with
admin rights)
3. Prefer to encapsulate resources in a local tree (easy to move / remove, or
whatever reason)
4. Yet another reason I may have overlooked
lessons learned are:
a. utilize the 'LIB= argument when creating your makefile
example: perl Makefile.PL LIB=/users/george/myperlprogram/lib/
b. avoid the temptation to tweak @INC (purported to make use of that library
location)
...and instead utilize 'use lib'
example: in MathServer.pm and MathClient.pm (for my projects purposes)
use MathSystem
becomes
use lib MathSystem
c. then we discovered an even better way is:
example: perl Makefile.PL LIB="./lib/" ## ie. use a relative
path...
which makes it OK to :
use MathSystem ## no need for
'use lib MathSystem'
Resulting benefits: No need for admin rights to install, no need to push a path onto
@INC at runtime
