The installation file can be found here:

http://www.komputika.net/maemo/

(the file you need is: mc_4.6.1-2_armel.deb )

I can't remember what dependencies are needed for the program, but you can do what I usually do: run the installer and wait for error messages to come up (if any). I bet that, if any libraries are missing from your system, you can find them on the same site.

For additional information, go to
