Actually, it seems that this package does not provide the regular .PL 
file expected by cpan.
I found out a way to generate it, and I could compile. But as you can 
see it uses perl native (I get an x86-64 build), and it's trying to 
install on my / directory instead of the rootfs:

FWIW, I can do the manual operations in qemu so it's really a matter of 
using target perl instead of hosted perl I think :(


I'm investigating a little bit more or I will post additional 
information for help :)

Thanks anyway,
