shared perlbrew running as root

[rootcho]

I have perlbrew installed in one of my user accounts and what to be able to use it from root.
I configured root ./.bashrc to have :

export PERLBREW_ROOT=/home/userx/perl5/perlbrew
source $PERLBREW_ROOT/etc/bashrc

also :

root# perlbrew list
* perl-5.17.8

So far so good I can run perl scripts from bash-console as root
The problem is if I try to run perl script inside a bash script, I get complains about modules not found :

Can't locate Time/HiRes.pm in @INC (@INC contains: /home/userx/perl5/perlbrew/perls/perl-5.17.8/bin/../lib /usr/local/lib64/perl5 ...

And yes if I try to do :

root# perldoc Time::HiRes
Can't find any loadable formatter class in Pod::Perldoc::Toman Pod::Perldoc::Toman ...

But if I check in my userx account I can see the package here :

/home/userx/perl5/perlbrew/perls/perl-5.17.8/lib/5.17.8/x86_64-linux/Time

And of course doing perldoc Time::HiRes from usex account works.

userx$ cpanm Time::HiRes
Time::HiRes is up to date. (1.9725)

What could be the problem... it seems like PERLLIB problem ? and how to solve it..
thanks

PS> And of course I have this in the bash script :

export PERLBREW_ROOT=/home/userx/perl5/perlbrew
export PERLBREW_HOME=~/.perlbrew
source ${PERLBREW_ROOT}/etc/bashrc
