| Subject: | Misleading warning if no network access... |
Run the example from the top of the perldoc on a machine without network
connection:
Use of uninitialized value $html in pattern match (m//) at
/usr/share/perl5/Net/MAC/Vendor.pm line 243.
Adding a working http_proxy env var makes the warning go away. I suggest
the warning text could be more descriptive of the actual problem.
