[mpich-discuss] cli.h file not found error

[kishor kharbas]

Hi Pavan,

Even cpi program displays the same error message.
Yes, these errors occur irrespective of whether with checkpointing or
without checkpointing.

Reverting back to mpich2-1.2 and using mpdboot-mpirun does not give these
errors...

Thank you.
