Clarification: kmod is used specifically with the `-k` switch of lspci:

        $ ash-euses -o pciutils:kmod
        sys-apps/pciutils:kmod - Enable sys-apps/kmod support for the -k switch
        in lspci command

This causes the LIBKMOD variable to be passed to the Makefile [1, 2]:

        pemake() {
            emake \
                [...]
                LIBKMOD=$(multilib_native_usex kmod) \
                [...]
                "$@"
        }

Anyway, with regards to your problem: if you're just installing your system now,
then you're probably getting this error  because  `/lib/modules`  doesn't  exist
inside your chroot.  This path is hardcoded into pciutils  [3];  this  has  been
modified by some vendors of the package, but not Gentoo [4].  You needn't  worry
unless you're still getting this error  outside  of  your  chroot,  once  you've
completed the installation. Just focus on building a kernel for now.
