Try this:
calibre = pkgs.lib.overrideDerivation pkgs.calibre (o: {
nativeBuildInputs = o.nativeBuildInputs ++ [ pkgs.pythonPackages.pycrypto ];
});
This is necessary due to the confusing handling of buildInputs and
nativeBuildInputs in mkDerivation: when not doing a cross-build, buildInputs is
passed to the builder via the $nativeBuildInputs environment variable, and
$buildInputs is empty. It would be better if this remapping were done in the
builder itself so that overrideDerivation would work as expected.
