Are you sure you're comparing the same things here? Using a tool like cpan/cpanm installs dependencies, running `perl Makefile.PL` does not. LWP::UserAgent has many dependencies.	[reply] [d/l]

Yes, the manual install lets you know the dependencies, I then download those and install them. The manual process to get all dependencies, gunzip - untar - build - test - install is still faster than cpanm doing it. Also, I have been using cpanm --verbose which shows the install of each dependency, it gets 'stuck' at the same place for each dependency as well.	[reply]

~~Well, this is great news, regardless of install method (manual/cpanm) you've discovered the point at which this weird pause occurs.~~ Could you please post an example of this? Update: Nope. Strikeout. See below.	[reply]
