I still have that:

cpan[4]> o conf makepl_arg
    makepl_arg         [PREFIX=/home/vlefevre SITELIBEXP=/home/vlefevre/lib/site_perl LIB=/home/vlefevre/lib/site_perl INSTALLMAN1DIR=/home/vlefevre/share/man/man1 INSTALLSITEMAN1DIR=/home/vlefevre/share/man/man1 INSTALLMAN3DIR=/home/vlefevre/share/man/man3 INSTALLSITEMAN3DIR=/home/vlefevre/share/man/man3]
Type 'o conf' to view all configuration items

but this no longer has any effect. When I want to install Sys::Info,
I get errors:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
ERROR: Can't create '/usr/local/man/man3'
mkdir /usr/local/man/man3: Permission denied at /usr/share/perl/5.14/ExtUtils/Install.pm line 494

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
 at /usr/share/perl5/Module/Build/Base.pm line 3578

Then I tried:

$ cpan
cpan> o conf makepl_arg INSTALL_BASE=/home/vlefevre
cpan> o conf commit
cpan> install Sys::Info

and ditto with

  o conf mbuild_arg --install_base /home/vlefevre

as suggested on http://stackoverflow.com/questions/251705/how-can-i-use-a-new-perl-module-without-install-permissions
and on http://stackoverflow.com/questions/9409888/when-using-cpan-in-linux-ubuntu-should-i-run-it-using-sudo-as-root-or-as-my-de

Same problem.
