make: *** No rule to make target `/usr/lib64/perl5/Config.pm', needed by `Makefile'. Stop.

All,

I am trying to install the OCS NG agent on a RHEL 6.x and I am getting the following error after the first steps:

# perl Makefile.PL

# make

Ocsinventory-Unix-Agent-2.1.1]# make install
make: *** No rule to make target `/usr/lib64/perl5/Config.pm', needed by `Makefile'.  Stop.

Am I overseeing the obvious?

Thanks,
Martin
