 If I try to extract nco with the netcdf4 variant but netcdf has not yet
 been installed, an error occurs:

 {{{
 $ sudo port extract nco +netcdf4
 --->  Computing dependencies for nco
 --->  Fetching nco
 --->  Verifying checksum(s) for nco
 --->  Extracting nco
 Error: Target org.macports.extract returned: couldn't execute
 "/opt/local/bin/nc-config": no such file or directory
 Error: Status 1 encountered during processing.
 }}}

 nco should not attempt to run nc-config, or anything else provided by a
 dependency, until the pre-configure phase; before that phase, the
 dependency may not yet have been installed.
