Can't locate ActivePerl/PPM/InstallArea.pm in @INC (@INC contains: /tmp/perl---------------------------------------------please-run-the-install-script---------------------------------------------/site/lib /tmp/perl---------------------------------------------please-run-the-install-script---------------------------------------------/lib .).
BEGIN failed--compilation aborted.
