If your library lacks an 'ncmpi_wait', then the nonblocking routines
were not built for some reason.  

In the pnetcdf config.log, there is a check for three MPI functions
that are needed for the nonblocking routines: MPI_Request_get_status,
MPI_Type_dup, and MPI_Info_dup.

If you have a very old MPI implementation (MPI-1 only), then these
routines might not be available.  More likely, when configure tries to
build the tests for these routines, there is some library or include
file missing.  

Can you post your config.log somewhere?  Or email it to me (just me:
it's a bit too big for posting to the list).
