Perl Makefile.PL fails

After downloading and un-tarring the latest version of rtir, I cd into
the rtir directory and run perl Makefile.PL.

This is the error i get:

[root@nssrt rtir-1.1.5]# perl Makefile.PL
include /root/rtir-1.1.5/inc/Module/Install.pm
Cannot autoload main - main::AUTOLOAD at
/root/rtir-1.1.5/inc/Module/Install.pm -
/usr/lib/perl5/site_perl/5.8.5/Module/Install.pm line 45.

I double checked the Module-Install here:

[root@nssrt rtir-1.1.5]# perl -MCPAN -e 'install Module::Install’
CPAN: Storable loaded ok
Going to read /root/.cpan/Metadata

Module::Install is up to date.

Has anyone seen my problem?
