Hello!
Just wanted to drop a line and say that I'm still working on this. 🙂
Sorry, I'm a little bit of a sloth sometimes.
All of the patches that were previously being applied by the last
maintainer have since been merged into upstream. Also, mp3gain has since
seemingly abandoned its own fork of mpg123, making things waaaay easier.
I was able to get mp3gain to compile against Debian's own mpg123 package.
Next will be making any updates necessary to manpages/documentation and
other package-related stuff.
Scott
