Why did you do that ?

gcc-3.0.1 is included in standard Mandrake 8.1; you should have it already
installed or on your CD's, as I have.

Else download:

lftp ftp.edisontel.it/pub/Mandrake_Mirror/Mandrake/8.1/i586/Mandrake
/RPMS/
get gcc3.0-3.0.1-1md.i586.rpm

On my system (with no extraneous rpm's added) it is under
/usr/bin/gcc-3.0.1

There is an /etc/alternatives directory in which a link is found between
gcc and the gcc you wish to use, you can change that if you like, or you
can simply do

export CC="gcc-3.0.1"
export GCC="gcc-3.0.1"

in your shell before compiling.

When I do update.packages() the only package it updates is mgcv, which it
then proceeds to compile and install with gcc-3.0.1 (even though my
'default' gcc in the alternatives directory is 2.96) (it seemed a clever
idea at the time to compile with gcc 3.0.1 rather than an earlier version
- not so sure it was now).

Guess you just have to install the

gcc3.0-3.0.1-1mdk.i586.rpm

RPM package from mandrake (your old gcc won't be touched) or else
recompile the RPM from source with your gcc-2.96.
