Thanks Jeff,
I have tried with openmpi-4.1.4, but I still get the same error. The main
error being
../../../../../../opal/mca/event/libevent2022/libevent/signal.c:135:14:
error: ‘NSIG’ undeclared (first use in this function); did you mean ‘_NSIG’?
  int ncaught[NSIG];
              ^~~~
              _NSIG
But I notice that inthe file "/usr/include/x86_64-linux-gnu/asm/signal.h"
there is some definition of NSIG
#define NSIG        32
typedef unsigned long sigset_t;
....
....
/* These should not be considered constants from userland.  */
#define SIGRTMIN    32
#define SIGRTMAX    _NSIG

So I am wondering if it is my system which is not picking up the correct
version of signal.h
I have a attached a new zipped file ompi-output-tar.bz2, which is also on
dropbox, link
