xargs: xgettext: No such file or directory
Couldn't generate POT file!
At first it didn't make sense. I couldn't figure out why it wasn't finding my plugin directory or file. It hadn't donned on me that the file which couldn't be found was actually xgettext.
I'd assumed I already had gettext installed. I know it's installed on at least one of the machines around here.
In any event, took less than 5 minutes to fix by installing gettext.
sudo apt-get install gettext
