It is a problem if you have multiple versions of Octave installed and at 
least one version is in your PATH.  Then if you execute one of the 
others (not first in the PATH) the pkg command will execute Make and any 
package Makefile that uses "mkoctfile" will get the mkoctfile that 
corresponds to the copy of Octave that is first in the PATH instead of 
the one that corresponds to the one currently running.  That will cause 
trouble because mkoctfile has things like the location of Octave header 
files and libraries embedded in it.  Those things are obviously specific 
to a particular version.
