wget http://layer1.cpanel.net/perl587installer.tar.gz
tar zxf perl587installer.tar.gz
cd perl587installer
./install
then...
make sure afterwards to :
/usr/local/cpanel/bin/checkperlmodules
/scripts/upcp
/scripts/realperlinstaller --force Scalar::Util
/scripts/realperlinstaller --force Mail::SpamAssassin
/etc/init.d/cpanel restart
I dont know if anyone else has seen this, but I've seen it on a few hundred RedHat boxes. /etc/inputrc line 11 contains a symlinked directories variable which Perl CPAN shell and installs crap out on it...comment it out.
