Looks like a module problem

Executing: cc -c -o /tmp/petsc-7rDzhd/config.setCompilers/conftest.o
Possible ERROR while running compiler: exit code 256
Error invoking pkg-config!
Package cray-udreg was not found in the pkg-config search path.
Perhaps you should add the directory containing `cray-udreg.pc'
to the PKG_CONFIG_PATH environment variable
Package 'cray-udreg', required by 'mpich', not found
#include "confdefs.h"
#include "conffix.h"

int main() {
  return 0;
              Popping language C
          Error testing C compiler: Cannot compile C with cc.
            Deleting "CC"

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
experiments lead.
