Fix several bugs

Bugs:
- 'version' in package section of config file is now working as expected
  for packages that is not binary;
- Fix stupid "version != '4.4.1'" bug in Netcdf_fortran;
- Since the static libraries of Netcdf_fortran are enabled, we also need
  to specify the location of Curl, Zlib and Hdf5 locations;

Other changes:
- Switch subcommand now pick up the latest version of packages that have
  multiple versions;
- Report subcommand now print version number;
Merge branch 'hotfix/1.0.0-a3'
