Yes, but I don't see how it's possible that cpan.org would serve out an outdated copy of the module. I figured there must be some local configuration that is telling it which mirror to use.

But I just looked at the build log. It says: Fetching http://www.cpan.org/authors/id/J/JL/JLMARTIN/Paws-0.41.tar.gz So why would cpanm download an older version of this distriubtion? It should be downloading Paws-0.42, shouldn't it?

Look at 02packages.details.txt:

Paws                               0.41  J/JL/JLMARTIN/Paws-0.41.tar.g
+z
Paws::AccessAnalyzer              undef  J/JL/JLMARTIN/Paws-0.42.tar.g
+z
[download]

The clientas show:

marto@marto-laptop~ $ sudo cpanm --info Paws
JLMARTIN/Paws-0.41.tar.gz
marto@marto-laptop~ $ sudo cpanm --info Paws::AccessAnalyzer
JLMARTIN/Paws-0.42.tar.gz

marto@marto-laptop~ $ cpan -D Paws

can confirm. Both cpanm --info Paws and cpanplus l Paws indicate that the Version on CPAN is 0.41 …
probably some missing index file or so.
