problem installing gcc 2.95.2

Hi,

I followed the instructions to install gcc 2.95.2
but encountered the following problem:

[67]# make bootstrap
make[1]: Entering directory `/disks/chestnut1/local/gcc-2.95.2/libiberty'

I've tried several different options, including the method
of installing multiple gcc's. But, none of them worked.
Could you tell me how to get around the problem?
Thanks a lot.
