Prefixed Gentoo does not create the /usr/lib -> /usr/lib64 symlink as in normal Gentoo. This blocks the portage ccache feature because ccache uses /usr/lib64/ccache/bin and /usr/lib/portage/bin/ebuild.sh only checks whether the directory /usr/lib/ccache/bin exists.
Imho it's better to fix ebuild.sh
It might be that baselayout should create this symlink, but maybe it does only for mulitlib systems. Can you run emerge --info?

ok, then it's time for me to check baselayout-prefix, and most probably make a new version bump that is based on the normal baselayout.
I'd add to that that there is still my old proposal to have a proper policy toward /usr/libexec, and then install ccache (and distcc) _there_, that would solve the issue. Or we could fix this by adding ccache and distcc to multilib ignore, and let them install _always_ on /usr/lib if portage looks for them there; it also makes sense for them not to be ABI-limited, anyway.
That's all fine with me, but for prefix I just follow the main tree, which for this bug means that baselayout should create the symlink if it does that in the main tree as well.

Reopening... I've tried to nail down to root of the problem on amd64-linux. Following http://www.gentoo.org/proj/en/gentoo-alt/prefix/bootstrap-linux.xml the command $ ./bootstrap-prefix.sh $EPREFIX portage creates /usr/lib/portage/. During the following steps $ emerge --oneshot --nodeps baselayout-prefix tries to create the required symlinks using "dosym" but fails when hitting the already existing /usr/lib directory. /lib64 -> /lib and /usr/local/lib64 -> /usr/local/lib are flawlessly created. The attached patch creates the /usr/lib symlink when bootstrapping the tree. Right now, I've only added x86_64-pc-linux-gnu. Other targets can be easily added.
Created attachment 147907 [details, diff] patch against r20135
ok, I made a similar patch to bootstrap-prefix.sh now. I hope this solves it for new bootstraps... (and for good, until we finally rid ourselves of the multilib hell)
