IIUC, the problem is that the system in question had a librt.so.1 but
not a librt.so. Wherever those might be -- /lib or /usr/lib -- doesn't
seem to be relevant, dlopen() should find them in either place.

So, I don't the patch Stelian pushed fixes things:
   (define-foreign-library librt
  -  (:linux (:or "librt.so" "/usr/lib/librt.so")))
  +  (:linux (:or "librt.so" "/lib/librt.so.1")))

(:or "librt.so" "librt.so.1") seems to be the right way to go.
Actually, make that (:or "librt.so.1" "librt.so") since version 1 is
what we've been testing with and that's probably the version we'd
rather load should a potentially incompatible version 2 appear at some
point.
