FWIW, this is caused/exposed by (quoting NEWS): - Fix long standing bug that caused compiler checks for Fortran and C++ compilers to run twice. I think the fix is right, and you've found a good workaround already, too. However, it might cause issues for quite a few more packages out there. I'm not sure what the best thing to do would be, but at the least documenting it more prominently would seem prudent.
