Accessing derivation build chroot

Hi,

I want to debug why a testcase from inetutils package fails.  For
this, I am running 'make check' in the derivation build directory
'/tmp/nix-build-inetutils..drv-1' after sourcing a new bash with the
'environmental-variables' file present in the same directory.
However, here the tests pass.  So I came to the conclusion that
something is amiss in the chroot used to build this derivation.  Any
hints to how I can access the chroot to run the tests from there?
