cpanm --sudo installs to /root/perl5 instead of /usr

1arryb has asked for the wisdom of the Perl Monks concerning the following question:

Hi, Monks

I have been using this script to install system perl modules and, up until trying it on an FC14 installation, it's worked great. On the new machine, however, it installs modules under /root, which isn't supposed to be the --sudo cpanm behavior. According to the App::cpanminus perldoc:

cpanminus at a boot time checks whether you have configured local::lib, or have the permission to install modules to the site_perl directory. If neither, it automatically sets up local::lib compatible installation path in a "perl5" directory under your home directory. To avoid this, run the script as the root user, with "--sudo" option or with "--local-lib" option.

I have tried it as root with and without --sudo, and cpanm will not install into /usr on this mahcine.

What am I missing?

Thanks, Larry

What am I missing? Perhaps it's just the way that the particular perl has been configured. Try running the following script (using the perl that's giving you the problem): `use strict; use warnings; use Config; for(keys(%Config)) { print "$_ : $Config{$_}\n" if $_ =~ /install/i; }` [download] That should give you a listing of where perl wants various things to be installed. (Don't be worried if some of the keys are unset.) Cheers, Rob	[reply] [d/l]

What am I missing? Probably some kind of Config entry -- see `perl "-V:.?usr.?"` and `perl "-V:install.*"` -- it all works off of Config and these overrides Re: CPAN won't install into personal directory; probably an o conf problem, Re: My favorite pitfall: setting up CPAN perl -I/home/user/stuff/lib/perl5 -S myfoobar.pl perl -M lib=/home/user/stuff/lib/perl5 -S myfoobar.pl export PERLLIB=/home/user/stuff/lib/perl5 myfoobar.pl export PERL_MM_USE_DEFAULT=1 export PERL_MB_OPT=--install_base /home/user/stuff export PERL_MM_OPT=INSTALL_BASE=/home/user/stuff export AUTOMATED_TESTING=0 cpan -fi Module Module Module Module Module Module cpanp -i Module Module Module --allow_build_interactivity=0 --skiptest=0 --force --prereqs=1 --no_update=1	[reply] [d/l] [select]
