There are two different ebuild for what I think it is the same program: sys-apps/tpctl and sys-apps/thinkpad. tpctl is more updated (4.2) than thinkpd (4.1). Reproducible: Always Steps to Reproduce: emerge search thinkpad emerge search tpctl Actual Results: Duplicate package in portage. Expected Results: There can be only one :-)
Do they actually give the same files? thinkpad is supposed to be the kernel modules, and tpctl is the userspace tool that interfaces with them. Check out /var/db/pkg/sys-apps/{thinkpad,tpctl}*/CONTENTS and tell me if they are different. They should be, and they are on my system.
I haven't emerged them, but as you say they have different files in your system. I am reading the descriptions again and they are what you said. Sorry.
Ok, killing bug :)
