It will do, but 'the homebrew version of R' is not anything official and 
you would probably do better to ask on R-devel since you are treating OS 
X as another Unix-alike.

The package has a broken configure, and has been reported to the 
so-called maintainer long ago.

You omitted the line with the error.  On my (native OS X) system you can 
see the log at 
http://www.r-project.org/nosvn/R.check/r-devel-macosx-x86_64/ncdf4-00install.html 
. Note the link command there:

clang -mtune=native -dynamiclib -Wl,-headerpad_max_install_names 
-undefined dynamic_lookup -single_module -multiply_defined suppress 
-L/usr/local/lib -o ncdf4.so ncdf.o ncdf2.o ncdf3.o src_ncdf4.o 
-Wl,-rpath, -L/usr/local/lib -lnetcdf -lhdf5_hl -lhdf5 -lm -lz -lcurl 
-L/Users/ripley/R/R-devel/lib -lR -dylib_file 
libRblas.dylib:/Users/ripley/R/R-devel/lib/libRblas.dylib -Wl,-framework 
-Wl,CoreFoundation

The use of -Wl,-rpath, is simply wrong and swallows -lnetcdf.  So you 
need to correct it.

One way to do so is to unpack the sources, try to install, copy the 
PKG_LIBS from src/Makevars to src/Makevars.in, correct it and try again.

I have in src/Makevars.in

PKG_LIBS= -L/usr/local/lib -lnetcdf -lhdf5_hl -lhdf5 -lm -lz -lcurl

but your mileage may differ (and probably will if you have a dynamic 
libndetcdf).
