[Jan Moringen (scymtym)]

The type has been removed in commit 101ab291060383d7a9a97131d78d9ce852d36885 which states:

  It's just a deftype to BIGNUM.

Using CL:BIGNUM instead of SB-BIGNUM:BIGNUM-TYPE should resolve the issue.

Note that the SB-BIGNUM package is internal and its exported symbols present an interface for other parts of SBCL, not for public consumption.
