package install error

[Clinton Winant]

Trying to install package signal, this requires various other package 
which, in turn require package struct.  When attempting to install 
package struct:

octave:1> pkg install struct-1.0.10.tar.gz
make: /usr/bin/mkoctfile: Command not found
make: *** [fields2cell.oct] Error 127
'make' returned the following error: make: Entering directory

Other package install have failed because of missing dependencies, but 
not in this way.  Suggestions to either address@hidden   or 
address@hidden   will be appreciated
