run the 'proj' command and see it convert something for you. probably
it's fine. the nad2nad missing issue will be a problem if you do datum
shifts in your work. getting datum support is trickier than it should
be. you have to download the separate proj-datumgrid-1.4.zip file and
unzip it into the ./nad directory in the proj4 source. (yeah) then
recompile and reinstall

perhaps, though you got things to work in the end. generally package
installs should be silent and deadly and noise indicates something
awry. not a postgis/proj issue though.

64bit should work fine in this day-and-age, and compiling from scratch
is the best way to ensure your software actually is running 64bit.
