Just pass --with-libgcrypt-prefix=3D$HOME/.guix-profile/lib.

The code corresponding to the check above is simple-minded (it=E2=80=99s in
m4/guix.m4).  All it does is:

  guile -c "(dynamic-func \"gcry_md_hash_buffer\" (dynamic-link \"$LIBGCRYP=
T\"))"

and checks its return code.

Passing --with-libgcrypt-prefix allows it to work with non-standard
prefixes.

Perhaps README should be augmented?
