[netCDF #GOM-132438]: NC Utilities version numbering

Hello Mark,

The .libs directory is created by libtool during the compile process; it is 
used to store shared objects when building libraries.  When building an 
executable it places a wrapper script in /ncdump and the actual executable in 
/ncdump/.libs.  See section 3.3, "Linking Executables", on the following page:

http://www.gnu.org/software/libtool/manual/libtool.html

As to your issue; that is very peculiar.  I repeated your steps with netcdf-c 
4.3.2 and did not encounter this issue.  I wonder if you have an older 
libnetcdf or netcdf.h on your system, which is being picked up during runtime?  
You might try recompiling, passing the '--disable-shared' option, and check the 
reported version after that, as well as inspecting your system for older 
extraneous files.

If this doesn't fix the issue, would you send me your config.log to look at? 
I'll see if anything stands out there.

Thanks, have a great day,

-Ward
