Build failure on Red Hat Linux 6.1

[michael dot collison at conexant dot com]

I download the latest release (libstdc++-2.90.8.tar.gz) and tried to build
with gcc-2.95.2:
In the gcc source directory I did the following (per the directions):

- mv libstdc++ libstdc++-v2
- mv libio libio-v2
- gzip -dc libstdc++-2.90.8.tar.gz | tar xf -
- ln -s libstdc++-2.90.8 libstdc++
- ./configure --prefix=/usr/local --enable-languages=c++
- make bootstrap

During the build 'gcc' and 'g++' build fine. When it comes time to build
libstdc++ I get the following:

Configuring in i686-pc-linux-gnu/libstdc++
ChangeLog      ..linked

iostream.h          ..linked
new.h          ..linked

..... (and many similar lines)

Finally the error message:

creating cache ./config.cache
configure: error: can not find install-sh or install.sh in .. ./..

The build has created a subdirectory under 'gcc-2.95.2' called
'i686-pc-linux-gnu'. Under that directory is 'libstdc++'. Naturally there
is no 'install-sh' (which lives under 'gcc-2.95.2'). Any ideas on how to
fix this?
