I can't seem to find a specific answer on this...

I'm trying to install FXRuby, which apparently requires Fox to be
installed first, in order to run a Ruby program called IFMapper.

I'm running Mac OS X 10.5.6 and installed Ruby (though it does come
with the OS, so I'm not sure if that messed something up).

When I try to install Fox using this method:

I get this (last few lines)...

I tried to just "make" first then do "make install", both using sudo
in front of them.

I'm very new to using Unix/X11 (started yesterday), so maybe I'm just
missing something basic, but would appreciate any help.  Thanks.
