Subject: give "gem install" options for "ruby extconf.rb"

Hi!

I'd like to install ruby-netcdf, but my netcdf-installation is in a non-standard directory. Is there any 
possibility to call

gem install ruby-netcdf

with additional options so that the extconf.rb is called with an option like

ruby extronf,rb --with-netcdf-dir=/PATH/TO/NETCDFROOT

instead of plain

ruby extconf.rb



thanks for hints
