Checksum error in suitesparse

I’m trying to build Julia at commit 7ca1a9047a. It fails with the following error:

===============================================================================
  ERROR: sha512 checksum failure on SuiteSparse-ec4b40ad9c0490ebf0969a41d4f880620db3f6f9.tar.gz, should be:

I’ve tried deleting the file, running make cleanall and make distcleanall, but this doesn’t seem to help. How to resolve this error?
