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
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

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!
