There is a Trac instance setup for Proj4js at
http://trac.osgeo.org/proj4js/ where you can file tickets. I've also
put up a 1.0 release candidate there for testing recently. As for
getting laea working (and the others not validated) I would like to get
those fixed for the final release, it is a matter of finding the time to
do that.
Also for Robert's issue, if you use proj4js-combined.js or
proj4js-compressed.js, all of the files under lib/projCode are bundled
into the one file so you don't need to include the individual
projections. Also a minor point: the Proj4js.defs['EPSG:4326'] is
defined by default in the package so there is no need to include that
one, we should probably do the same the Google one as well, but it's not
there now so you do need to define that.
