[netCDF #ZVD-828686]: compile error cannot compute sizeof (off_t)

The default installation is in /usr/local/, so the library should be in 
/usr/local/lib/,
the header file should be in /usr/local/include/, and the utilities shuld be in 
/usr/local/bin/.  If you want things installed somewhere else, you need to use 
the
--prefix=/some/where/else option to configure.

If things are not where you expect, you could send us the config.log file to 
help
determine what happened.
