help with installing gcc in os x please.

[Ben Dougall]

so this is where it's gone wrong i think, at the make install stage.

while in the objdir folder i type make install (forgetting about my 
pword idea). this is the entire output of that:

[Ben-Ds-Computer:~/gcc/objdir] bend% make install
/bin/sh ../gccfolder/mkinstalldirs /usr/local /usr/local
(cd intl && make all)
make[2]: Nothing to be done for `all'.
for file in cc1 ; do \
   if [ -f $file ] ; then \
     rm -f /usr/local/lib/gcc-lib/powerpc-apple-darwin6.2/3.2.1/$file; \
     /bin/sh /Users/bend/gcc/gccfolder/install-sh -c  $file 
/usr/local/lib/gcc-lib/powerpc-apple-darwin6.2/3.2.1/$file; \
   else true; \
   fi; \
done

that's that's the error i got to start with, and because of the 
'permission denied' bit in that, and the fact that you have to input a 
password in os x whenever you want to install anything i arrived at the 
pword thing ('password' didn't work and i've seen pword used in 
conjuction with command line stuff somewhere else so i tried it and it 
seemed to work) so i thought i'd cracked the problem but now it looks 
like i hadn't.

maybe the problem goes back even further than the make install, to the 
make bootstrap bit? i really have no idea.
