Yikes... Sorry Michal.  I guess I dropped the ball on this one.
As a note to myself, the FAQ  

 http://trac.osgeo.org/proj/wiki/FAQ

says:

  After downloading and unpacking the PROJ.4 source, also download and
  unpack the set of datum shift files. This would be a file like
  ftp://ftp.remotesensing.org/pub/proj/proj-datumgrid-1.4.zip. This file
  should be unpacked within the proj/nad directory. Then proceed with the
  configuration, build and install. This will ensure that the build system
  knows about the grid shift files, and applies the ascii to binary
  preprocessing step.
