Problème d'installation de CPAN

Bonjour,
J'ai un souci lors de l'installation de CPAN sur mon systeme unbuntu:

cpan
Terminal does not support AddHistory.


Your configuration suggests that CPAN.pm should use a working
directory of
/home/cyrine/.cpan
Unfortunately we could not create the lock file
/home/cyrine/.cpan/.lock
due to permission problems.

Please make sure that the configuration variable
$CPAN::Config->{cpan_home}
points to a directory where you can write a .lock file. You can set
this variable in either a CPAN/MyConfig.pm or a CPAN/Config.pm in your
@INC path;
You don't seem to have a user configuration (MyConfig.pm) yet.
Do you want to create a user configuration now? (Y/n) [yes] y
mkdir /home/cyrine/.cpan/CPAN: Permission denied at /usr/share/perl/5.10/CPAN/Shell.pm line 656

keep the same shell
