Yes.

OK, so the RUNPATH is correct, but ghc-pkg expects a libgmp with an
older SONAME.

The correct fix would be to add the old GMP version that produces
libgmp.so.3 to multiprecision.scm, and to use that as an input to GHC.

According to <https://bbs.archlinux.org/viewtopic.php?id=94146>,
libgmp.so.3 may correspond to GMP 4.3.2.

So:

  (define gmp-4.3
    (package (inherit gmp)
      (version "4.3.2")
      (source (origin ...))))

And the use that in GHC.

HTH!
