Sourcing the Intel Fortran Compiler, errors, missing library?

[Killuah]

Well well, i got almost everything figured out. Only ONE thing left.

Ubuntu
I installed the intel fortran compiler
and sourced the compiler via
source /opt/...../ifortvars.sh ia32

in my bash.rc so the bash knows the compiler.
Now every time I try to compile something via

ifort test.f90
I get an error:

/opt/intel/Compiler/11.1/056/bin/ia32/fortcom: error while loading shared libraries: libstdc++.so.5:
cannot open shared object file

What am I missing?
The documentation says nothing about this :(

Turned out that the newest Ubuntu distro comes with
ibstdc++.so.6,
had to install 5 via oacket manager.
Jesus took me ages to figure that out.
