nx-3.0.0 should be fine of 64 bit.

You probably want to look a few lines earlier ;-) This is what it looks like 
on a 64bit FC7 box but your paths differ - see below.

NX_DIR=/usr
PATH_BIN=/usr/libexec/nx # if you change that, be sure to also change the 
public keys
PATH_LIB=/usr/lib64/nx
NX_ETC_DIR=/etc/nxserver
NX_SESS_DIR=/var/lib/nxserver/db
NX_HOME_DIR=/var/lib/nxserver/home

Looks to me like yo need:
PATH_LIB=/usr/lib64/NX/lib

Do you have both 32bit and 64bit nx libs installed? Check for symlinks and 
wrappers.

I think you need:
PATH_BIN=/usr/lib64/NX
