Make fails for Linux::Inotify2 on my system

shouldn't fail... (just tried it on Debian etch and it did build out of the box). What error are you getting?

Anyhow,

$ apt-cache search inotify2
liblinux-inotify2-perl - scalable directory/file change notification
[download]

reveals that there's also a debian package liblinux-inotify2-perl, which you could simply install.
