CPANを自分のホームに設定する方法

シェルでcpanって打って出る初期設定のときに

Every Makefile.PL is run by perl in a separate process. Likewise we
run ‘make’ and ‘make install’ in processes. If you have any
parameters (e.g. PREFIX, LIB, UNINST or the like) you want to pass
to the calls, please specify them here.

If you don’t understand this question, just press ENTER.

Parameters for the ‘perl Makefile.PL’ command?
Typical frequently used settings:

PREFIX=~/perl       non-root users (please see manual for more hints)

Your choice:

ここをPREFIX = ~/perlとかにしてやる

初期設定ミスった場合は
o conf makepl_arg PREFIX=~/perl
o conf init
でどうにかなるかも
