I get this message when running Sledgehammer:

The Perl module "libwww-perl" appears to be missing. You will need to install it if you want to invoke remote provers.
"remote_vampire": Error: SystemOnTPTP is not available.

I tried to add libwww-perl through the Cygwin setup, but it didn't show up in the setup.

Thanks for testing that unofficial integration-test snapshot. It shows that there was something wrong with the integration, namely the cygwin component.

This thread should have remained on isabelle-dev, though, where the development process happens, and everything is constantly moving -- hopefully forwards and usually quite fast. See also this change from 3 weeks ago:

updated cygwin -- include perl_vendor for libwww-perl;

Public testing of isabelle-users of Isabelle2014-RC0 should start at the end of next week. Until then the continued development happens at isabelle-dev.
