Sorry, I'm a bit cranky right now. My cpan disappeared while trying

1. LWP::UserAgent has been a prerequisite for years. But I think
I remember that it was temporarily removed from one of the older
platform specific build instruction pages.
2. Can you be more specific regarding your problems with
download_external_dependencies.pl so that I can fix it? It exists
under this name for more than two months and since it is used in
every setup of a build I would say that it is fairly well tested.
But that does not mean that it is error free.
He might have found something similar to this:

Hm, I did not perceive this as a persisting problem. It seemed to have
a simple solution.
He has LWP::UserAgent but it's too old, a method is missing, so he tries
to update the module with cpan. Updating Perl like this may brake other
things in your system, I prefer keeping the system as it came, and
install a local perl version.
If that is really the problem and updating Perl really is such a problem
(I never experienced it as one) then I could try to make the use of
LWP::UserAgent more compatible with older versions.
The biggest problem might be to lay hands on such old versions in a
running system.
IMO there is no fix for this: we check the perl version, we check the
presence of LWP::UserAgent, but: does it make sense to check the
LWP::UserAgent version too? Is it possible at all? The perl module does
not document when a specific method was introduced, or I least
I couldn't find that info in
http://search.cpan.org/~gaas/libwww-perl-6.04/lib/LWP/UserAgent.pm there
is not such thing as a @since tag.
First we have to identify this as a real problem. Then we (I, you, or
anybody else) are certainly able to find a solution. We might even use
an alternative to LWP::UserAgent.
