[R] Receive "unable to load shared object RNetCDF.o" during R INSTALL of RNetCDF

[David Brown]

On a Red Hat Linux cluster I am seeing the following after multiple
other packages were successfully installed. The error seems to suggest
that RNetCDF.o was not copied to the appropriate lib folder. The admin
user performing the install has the required privileges to perform the
install. Words of wisdom are greatly appreciated:

R CMD INSTALL --configure-args="--with-netcdf-include='/soft/local/netcdf/netcdf-3.6.2/include/'
--with-netcdf-lib='/soft/local/netcdf/netcdf-3.6.2/libso'
--with-udunits-include='/soft/local/udunits-2.1.23/include'
--with-udunits-lib='/soft/local/udunits-2.1.23/lib'"
