I think that you have not enough memory to execute `big' commands like
mined. Hit F1 to see how much free memory you have at a certain moment. If
the shell can't fork and/or exec a program, it reports with `: not found'
or `: cannot execute' messages. This also happens when the process table
is (almost) full! It helps to use `exec' because the shell then removes
itself from memory, thus providing somewhat more space for other programs.
