I decided to learn NSIS scripting for the first time today. It wasn't too bad. So I created yet another PidginPortable moonshine...
While I did most of the modifications myself, some elements are from dcaravana's PidginPortable. I decided to be fairly complete in replacing mentions of Gaim with Pidgin. This took a fair few hours...
Anyway, additional features include the actual installer source and a slightly more comprehensive (or verbose, if you will) installer. To build the installer yourself (see build.txt), you must run the installer to extract the files, then compile the NSIS script to package the files into an installer program. I know, this is weird.
Edit: Fixed "Portable Pidgin" typo in installer, brute force for best compression. It should be much smaller now.
