I found that I received the same "/etc/security/selinux/file_contexts: No such file or directory" message with the ntfs package but it installed properly anyway. I guess it is simply an informational message.
My network package source installs but still does not build. The make file complains about rules for bcm4400.o. I looked at the broadcom driver zip. It is old and does not mention fedora at all. I filled out a driver support request with broadcom.
If anyone has been succesfull with this driver please let me know. Otherwise I will post the reply from Broadcom.
