Why does Module::Build try to rebuild every time (or most of the time I'm not sure). See example: 

perl -e "use Module::Build"
(no errors)
curl -L https://cpanmin.us | perl - -M https://cpan.metacpan.org -n IO::Socket::IP
...snip...

Failed to upconvert metadata to 1.1. Errors:
Missing mandatory field, 'version' (version) [Validation: 1.0]
 at - line 32.

So even though Module::Build was installed it will always try to install again. I have noticed this behaviour for many packages. Why is this so? can it be prevented with some switch ?

I'm trying to install Mojolicious on OpenWRT and the native Module::Build intsalls fine but if I try to install via CPAN I get the error above. I want the Arduino YŚN community to have an alternative to Node.JS and Python !! Please help !

TIA
Alex
