[Emacspeak] Errors when Installing Emacspeak on Linux Mint

[Lanie Carmelo <laniegcarmelo@xxxxxxxxx>]

Hi all. I decided to switch distros to Linux Mint, so I'm in the process 
of installing Emacspeak there. Everything has gone well until I tried 
typing make in the emacspeak folder. Typing "make config" worked without 
a problem, but when I type "make", I get this:


In toplevel form:
emacspeak-calibredb.el:50:1:Error: Symbol’s function definition is void: 
keymap-unset
make[1]: *** [Makefile:53: emacspeak-calibredb.elc] Error 1
make: *** [Makefile:44: emacspeak] Error 2


I'm not sure how to fix this error. Can anyone help? Thanks.
