Hmm... the code does claim to handle multiple -P options.

Sorry to hear this is giving you trouble.

I know that the parsing for this option is maybe a bit janky and could 
use some improvement, but it can be made to work.

Firstly: -P is followed by a single string, so you should use the syntax 
Marco confirmed as working, i.e. package names separated by only a comma.

If you can point out where our documentation suggests space-separated 
names can work, I'll get that fixed.

(There's obviously some bug adding to the confusion here as the 
non-options 'perl-CPAN-Meta-YAML' and 'perl-CPAN-Reporter' are being 
silently ignored by setup.)

checking /var/log/setup.log.full afterwards (or drop cygstart and add -B 
so you can see the output of setup)

Likewise, also seems to add the requested packages.

One email thread, one issue, please.
