Pascal,

This generally means that your Ruby mapscript was built without PROJ.4
support.  I think you need to rebuild ruby mapscript ensuring that PROJ.4
support is enabled during the full build of mapscript and the underlying
mapserver library.  I'm guessing that your mapscript and mapserver cgi are
not from the same build.

PS. MapServer is still very active, though perhaps Ruby Mapscript is only
lightly used.
