Bugzilla Bug 80176

The valgrind-2.2.x ebuilds (correctly) remove the net/if.h include from
vg_unsafe.h if a version newer than 2.6.7 of the Linux headers are installed.
However, the check is only performed for sys-kernel/linux26-headers, not for
sys-kernel/linux-headers. Ebuilds need to be updated accordingly.
The relevant ebuild section is:

        if has_version '>=sys-kernel/linux26-headers-2.6.7' ; then
                einfo "Removing net/if.h from the includes in vg_unsafe.h"
                sed -i -e "s:#include <net/if.h>::" \
                        coregrind/vg_unsafe.h ||die
        fi

A very quick fix would be to duplicate that section and put linux-headers
instead of the linux26-headers in the duplicated section. That works just fine
for me in my overlay.

This shouldn't be an issue right now, because 2.6.x versions of linux-headers
are masked. However, I'll add a fix the next time I update the ebuild.

Thanks for bringing this to my attention.

Fix included in 2.2.0-r2

Reopening to change resolution from REMIND to FIXED.
Otherwise it will stay on my buglist.

Done
