Possible kink in going with a newish Linux distro. Kindlegen. Tried it under RHEL7 and, unlike under RHEL6, it refuses to function. The only work around it to futz with Wine and various environment variables to make the Windows version work. If this holds true for newish distros, I am screwed. I have to use it often.
It's like the universe is pressing me to just buy a new iMac and be done with it. The Mac version of kindlegen works fine.
Damnit.
