You can go to http://www.census.gov/geo/www/cob/zt_metadata.html, download
the Arcview shapefiles by state, import them into sas using proc mapimport,
then concatenate the individual files to make a single map dataset. You will
have to write some code to add some class vars and set up the individual map
dataset before or during concatenation. You can then project the maps using
proc gproject if needed. I don't remember what projection the maps are in
but I think they are just raw lat/lon.
I used some of these maps a few months ago and the process wasn't very
difficult. The worst was reaquanting myself with the format used for SAS map
datasets so that everyting works correctly during concatenation of the
individual state files. Once this is done you should be able to use the new
zipcode map with proc gmap just like you would a SAS supplied map.
