Actually, this is a known problem with linux_base-fc4 and 2.4.2
emulation. It pops up on the mailinglists now and then so it's starting
to become a faq.

One of the solutions is to create a softlink:

ln -f ../../lib/librt.so.1 /compat/linux/usr/lib/librt.so.1

That way, the linux compat open(2) syscall never returns the FreeBSD
librt.so.1 and the linker eventually finds the 2.4.2 compatible version
/compat/linux/lib/obsolete/linuxthreads/librt.so.1.

Somebody should at this to a post-install target in the port/package,
because /compat/linux/bin/ls and some others are affected as well.
