hmm not necessarily the way to go (restraining myself from saying
'definitely bad bad bad')... have you seen all the linux-* ports in /usr/ports?

(and do you REALLY need ALL of the rpms in FC4? )

Ockam's razor says you simply stuffed up the system so much it's beyond
recognition.
I suggest reading the FBSD Handbook, including the section about linux
compatibility (and believe the handbook, that is all you have to do to have it
working!), then give this computer another chance by reinstalling.

I'll say it again - there is NO need to touch libmap.conf when setting up
your run of the mill linux compat. you may *have* to in some cases, but I
haven't had to yet in several years of using linux compat.

you need to install from emulators/linux_base-.... pick your own. 

Wipe the machine and start again :) that's how we all learnt ;)

good luck!
