I don't know of a quick fix (other than not to use anything other than
the RedHat kernel). The glibc on RedHat has been compiled with glibc
support and that causes many programs not to work with a standard
kernel.
You can use:
LD_ASSUME_KERNEL=2.4.1
(with the redhat kernel, at least) to have the redhat not use ntpl (but
instead use
Linuxthreads with floating stacks) ... but I haven't tried using it on a
non RedHat kernel.
