A kind soul has contributed a Debian/Ubuntu package for the innotop MySQL and InnoDB monitor. Thanks Sebastien Estienne!
You can find the package in the source directory. Sebastien wrote me that he tested it on Ubuntu Dapper Drake, and I just verified that it works on Edgy Eft.
Since I use Ubuntu on my own machine now, I may integrate this into my build process for future releases of innotop. But for right now, at least there’s another installation option.
