It should still be there. What options did you use when you
configured and compiled Octave? Did you install it, or try to run it
in the same directory where it was compiled? If the latter, and you
used --enable-lite-kernel, Octave won't be able to find the functions
defined in .m or .oct files until you install it (or set LOADPATH to
something other than the default).
