No; that's not for the user to decide; that's for the port author to  
decide. The octave port specifies that it requires the gcc40 port:

depends_run	bin:gnuplot:gnuplot	\
		port:gcc40

And in fact on Intel, it requires the gcc42 port:

platform darwin 8 i386 {
	depends_run-delete      port:gcc40
	depends_run-append      port:gcc42

It looks like this was changed a month ago:

You can ask the committer or the octave maintainer for more  
information if necessary. You can of course also play around with the  
portfile yourself, removing the gcc40 line, uninstalling the gcc40  
port, and seeing if it still works for you, and telling the committer  
and the maintainer about this if it does. Note that since this port  
has some variation between ppc and i386 hardware, it would be best  
for you to test on both types of machine, lest you break one or the  
other with your changes.
