cannot exec cpp0

[s dot kwiatkowski at t-online dot de (Sebastian Kwiatkowski)]

Hi,
I'm trying to upgrade egcs-1.1.2 to gcc 2.95.3 on a RedHat 6.2 box.
After installing it, I get (building anything):
gcc: installation problem, cannot exec `cpp0': No such file or directory

But actually cpp0 exists in /usr/lib/gcc-lib/i686-pc-linux-gnu/2.95.3

Could this problem have something to do with the conten of the following 
extract of the build log?
