two questions about building parallel netcdf

[Wei-keng Liao]

Hi, George

Please set environment variable LIBS, so the intel compilers can find the proper MPI library, i.e.
setenv LIBS "-lmpi"

Oh, also, It may just be that it cannot find MPI_File_sync.  So, maybe the problem is not that it is ignoring the disable, but, that the MPI-IO implementation is lacking something needed by parallel-netcdf.  Just wondering.

I saw a response somewhere when I was googling for help someone who seemed to be related to the project say, "who would want to do that?"  But, the problem is, MPT only creates shared libraries.  So, we need shared libraries, if we want it to work with MPT.
