install problem, GCC 3.0, RedHat Linux 2.2.18

[Brent Phillips <brent at lyrastudios dot com>]

Hi,

When building gcc 3.0, it build clean when the target directory is 
/usr/local/*.

However, the previous gcc installation (2.96) was in /usr/*, so I tried 
rebuilding gcc 3.0 with /usr/local/* as the target (using --prefix /usr/). 
But it breaks:

make[2]: Entering directory `/opt2/src/gcc-obj/i686-pc-linux-gnu/libjava'
/bin/sh ./libtool --mode=link /opt2/src/gcc-obj/gcc/xgcc

Please advise!
