Gerald / Sharon,

The PROJ.4 distributed from remotesensing.org installs a proj_def.dat
file containing:

<aea> # Conterminous U.S. map
<lcc> # Conterminous U.S. map

So, for the "aea" projection there are defaults lat_1 and lat_2 values.
I don't think I added them myself, so I imagine they come from earlier
versions distributed by Gerald, but I don't know that for a fact.  Anyways,
no longer is there a big mystery where the defaults were coming from.
