While I haven't compiled it myself, it seems that Rnetcdf requires a  
library that you probably don't have installed. Check out it's build  


Probably it's looking for the udunits (http://www.unidata.ucar.edu/software/udunits/ 
  (?)) library and you don't have it.

I just tried to compile ncdf on my machine, and it also failed ..  
looks like you need netcdf.h. Just look at the status/reporting that  
building the package gives:

checking netcdf.h usability... no
checking netcdf.h presence... no
checking for netcdf.h... no
checking /usr/local/include/netcdf.h usability... no
checking /usr/local/include/netcdf.h presence... no
checking for /usr/local/include/netcdf.h... no
checking /usr/include/netcdf.h usability... no
checking /usr/include/netcdf.h presence... no

I guess you just need to get the required libs and try again.

Or are you getting different errors?
