You should grep for RUNPATH, and I guess that will show that
/gnu/store/zv2c9mbs4q7f75p9xlgxs62fb5wmp3ac-granite-0.4.0.1/lib is *not*
in there, even though it should (if it=E2=80=99s not in RUNPATH, then launc=
hing
=E2=80=98granite-demo=E2=80=99 will result in a =E2=80=9Clibrary not found=
=E2=80=9D error, which is what
this validation phase wants to avoid.)

To fix this, you need to make sure the link command for =E2=80=98granite-de=
mo=E2=80=99
has an explicit -lgranite or similar; ld-wrapper will take care of
adding the corresponding -rpath switch.

HTH!  If needed, we can discuss it further on IRC.
