Hi John,
All I know is it is Eagle 5.7.0, I think mine is the professional version. Just look through your library under connectors, con-XXX.lbr, and check descriptions for 2mm pitch connectors, as long as they aren't SMD, they should be proper thru-hole style and the pad spacing should work, can't see why you couldn't duplicate the pads over and over to make a 2mm pitch protoboard layout.
Here's a *short* list of library files in my copy:
con-3m.lbr 3M Connectors
con-amp-champ.lbr IEEE488 (Centronics) Connectors from AMP
con-amp-micromatch.lbr AMP Connectors, Type MicroMatch
con-amp-mt.lbr AMP Connectors, Type MT
con-amp-mt6.lbr AMP Connectors, Type MT6
con-amp-quick.lbr AMP Connectors, Type QUICK
con-amp.lbr AMP Connectors
con-amphenol.lbr Amphenol Connectors
con-avx.lbr AVX Connectors
con-berg.lbr Berg Connectors
con-bosch.lbr BOSCH Automotive Connectors
con-chipcard-iso7816.lbr ISO 7816 Chipcard (Package)
etc, etc, etc, 77 connector libraries in all!!
