help with imaxima



I am using maxima  on rehat 7.3 and just installed imaxima according to 
the instructions on its web page. After starting an emacs session and 
typing M-x imaxima, I get the error message "Cannot open load 
file:imaxima". I suppose this means emacs cannot find imaxima. I have 
placed the imaxima directory in my home directory and compiled according 
to directions from the imaxima directory. The INSTALL notes say that the 
installation process is supposed to place files in /usr/local/bin. 
However, I can see no imaxima packages there after the installation 
procedure is finished. Am I being stupid and not seeing my errors?
Thanks for any help,
Dick Fell
