Hello, Arthur :-)

In all fairness, this may be a bug with get_iplayer,
caused by recent BBC changes.
First, this is not a typical podcast;
on http://www.bbc.co.uk/podcasts/radio4
most have download URLs of the form:
http://downloads.bbc.co.uk/podcasts/radio4/[programme]/[filename].mp3
e.g. for "Thought For The Day" May 29th it's:
http://downloads.bbc.co.uk/podcasts/radio4/thought/thought_20150529-1239a.mp3
GiP is best tailored to handle this type of podcasts.
However, lately another type of podcast has emerged,
like the one you're having trouble with and like "Home Front"
(http://www.bbc.co.uk/programmes/b047qhc2/episodes/downloads)
in which every episode is assigned a pid; GiP can't apparently
process those "podcast" pids.

Concentrating on your offending podcast,
its programme page is
http://www.bbc.co.uk/programmes/p02sgk0l
hence, as you said, pid=p02sgk0l
by loading:
http://www.bbc.co.uk/programmes/p02sgk0l/playlist.json
you'll find that vpid=p02sgk0w

At least on my setup, I'm finding that:

perl 
get_iplayer-292.pl --type=radio --pid=p02sgk0l --modes=flashaac --tag-podcast-radio 
 --force

works (from my Greek IP) ands yields an M4A file of your show.
So does

perl 
get_iplayer-292.pl --type=radio --pid=p02sgk0l --modes=hlsaac --tag-podcast-radio 
 --force

If you're not in the UK currently, please disable any geo-spoofing methods
you are using (if any), like "Smart DNS" services or proxy servers.
The HLS URL you've posted
http://cp143012-i.akamaihd.net/i/...
is of the UK (HLS) CDN, this hostname (cp143012-i.akamaihd.net)
is geo-blocked and won't connect from a non-UK IP.
But the podcast file IS AVAILABLE worldwide, it should
download via rtmp/hls from your overseas location!
(FWIW, the file downloads over AppleHLS via the international
version of the Akamai (HLS) CDN, "cp312012-vh.akamaihd.net")

 Now, GiP in its current incarnation can't download via PID the MP3 version 
linked
on the programme's page; if you examine (but not click) the link,
you'll see that it uses the mediaselector/5 API URL with a new mediaset 
string:

http://open.live.bbc.co.uk/mediaselector/5/redir/version/2.0/mediaset/audio-nondrm-download/proto/http/vpid/p02sgk0w.mp3

This new mediaset=audio-nondrm-download
is not hardcoded into the GiP script, so it can't generate
that download link from a given "podcast" pid...

Workaround:
1. Build or refresh the podcast cache by running:
get_iplayer --type=podcast -f --force
(takes a little while)
2. get_iplayer --type=podcast "Documentary of the Week Podcast"

returns (5 results in total):
