While doing an 'emerge system -U' linux-headers got updated from 2.4.21 to 2.4.21-r1. After that I wanted to recompile glibc. So I did: emerge glibc -v Calculating dependencies ...done! >>> emerge (1 of 1) sys-libs/glibc-2.3.2-r9 to / >>> md5 src_uri ;-) glibc-2.3.2.tar.bz2 >>> md5 src_uri ;-) glibc-linuxthreads-2.3.2.tar.bz2 >>> md5 src_uri ;-) glibc-2.3.2-branch-update-20031115.patch.bz2 * Checking for sufficient version kernel headers ... no * Could not find a kernel source tree or headers with * version 2.6.0 or later! Please correct this * and try again. !!! ERROR: sys-libs/glibc-2.3.2-r9 failed. !!! Function pkg_setup, Line 190, Exitcode 0 !!! Insufficient kernel headers present! I do have a 2.6.x kernel tree (check below). So why of a sudden doesn't glibc want to recompile? Some more informations: $ ls -l /usr/src/ insgesamt 4 lrwxr-xr-x 1 root root 11 7.

you need to setup your /usr/src/linux tree in other words, do what you have to do to make sure /usr/src/linux/include/linux/version.h exists ... perhaps `make menuconfig ; make` ?
Cool that did it. version.h was missing because I did "make clean" after compiling and installing the kernel.
