Installing with non-standard prefix fails - please help

[H_Jarausch]

Hi,

I need to install gcc-4.7-SVN onto a machine where I don't have root access.
I'd like to install with the  /kurs/cpp prefix. For doing so, I configure
like

CFLAGS='-L/kurs/cpp/lib' LDFLAGS="-L/kurs/cpp/lib -Wl,-rpath,/kurs/cpp/lib"
\
  ./configure --prefix=/kurs/cpp --enable-languages="c++" \
                  --with-gmp=/kurs/cpp --with-mpfr=/kurs/cpp
--with-mpc=/kurs/cpp

Still I get a configure error when the new gcclib is built:
configure:3540: checking for suffix of object files
configure:3562: /kurs/cpp/Src/gcc-4.7-110729/host-i686-pc-linux-gnu/gcc/xgcc
-B/kurs/cpp/Src/gcc-4.7-110729/host-i686-pc-linux-gnu/gcc/
-B/kurs/cpp/i686-pc-linux-gnu/bin/ -B/kurs/cpp/i686-pc-linux-gnu/lib/
-isystem /kurs/cpp/i686-pc-linux-gnu/include -isystem
/kurs/cpp/i686-pc-linux-gnu/sys-include    -c -g -L/kurs/cpp/lib  conftest.c
>&5
/kurs/cpp/Src/gcc-4.7-110729/host-i686-pc-linux-gnu/gcc/cc1: error while
loading shared libraries: libmpc.so.2: cannot open shared object file: No
such file or directory


There is a valid symlink  /kurs/cpp/lib/libmpc.so.2 to 
/kurs/cpp/lib/libmpc.so.2.0.0  and ldd /kurs/cpp/lib/libmpc.so.2.0.0 doesn't
show any problems.

So, what am I missing for building gcc-4.7-SVN in my case.

Many thanks for a hint,
Helmut.
