dpkg-buildpackage fakeroot vs sudo different results

[joneZ]

Hi,

I wanne make a package from XML:RSS::Feed module from cpan.

Now the Problem is that a test ( from original perl Makefile ) from that module goes
to a RSS-Feed and wanne read this and do some checks and fails under fakeroot.

here is that test that fails:

http://search.cpan.org/src/JBISBEE/XML-RSS-Feed-2.212/t/008_store_retrieve.t


It fails on ....

ok( $feed_title->cache, "Successfully Cached File" );

because it can't find http://www.jbisbee.com/rsstest




But when i do
dpkg-buildpackage -rsudo
it works like a charm ...

The test connects to that feed above and do some hardcoded test with that file.

But why pass the test with sudo and fail with fakeroot , is that normal ??

And can I upload packages with sudo, assuming that this is not good ...

Greetings and thx for some hints ...
Erik
