I succed with the portable gpodder 2.5 here http://portablelinuxapps.org/audiovideo/gpodder
i must install libsqlite3-0_3.6.22-1 via puppy packet manager and make a symbolic link : ln -s /usr/lib/libsqlite3.so /usr/lib/libsqlite3-3.6.12.so.0
because portablelinuxapps does not offer the portables anymore.
But yes, after following jplts instructions indeed gPodder started and was able to import my opml file wit the podcasts, but it won't download anything.
then I tried jPodder, which will install and download Adam Curry's opemning podcast but then the GUI freezes
puppy podcast grabber works like a charm but it does not show the information about the episodes of shows you want to download. I guess it wil be the same with pMusic: fast, lean but a bit too lean here.
so I would be very happy if somebody could provide me with a working gPodder for lucid & slacko...
