SOLUTION
It is recommended that all Gentoo Linux users upgrade their kernels.
If you are running any of gentoo-sources, gs-sources, pfeifer-sources
sparc-sources or xfs-sources updates are available. Sync your tree
and run emerge <package> to install the latest version of the
package. Then compile and install your new kernel and reboot.
If you are using an other kernel package which hasn't been updated or
download your own sources you can download a patch from
http://cvs.gentoo.org/~aliz/linux-2.4.20-ptrace.patch
and manually patch your kernel.
