Strange problem upgrading to 7.0.3x

Ever since I upgraded to 6.5.2 I've had problems upgrading to the 7.x
series. I'm running Red Hat 6.1 (2.2.17 kernel) on this box.

Now I'm trying to upgrade to 7.0.3 via the rpm. When I tried both the
freshen (-F) and upgrade (-U) switches, I found a failed dependency:
/lib/gcc! and a bunch of complaints that 6.5.2 needed some files being
replaced. So, the attempt failed.

I manually plucked all traces of the old 6.5.2 from the system and tried a
regular install:

[root(at)salmo rshepard]# rpm -ivh postgresql-7.0.3-1.i386.rpm
error: failed dependencies:
/lib/cpp is needed by postgresql-7.0.3-1
[root(at)salmo rshepard]# rpm -ivh --force postgresql-7.0.3-1.i386.rpm
error: failed dependencies:
/lib/cpp is needed by postgresql-7.0.3-1

Very strange! I _have_ /lib/cpp (for I've used it to build many
applications):

[root(at)salmo rshepard]# ls -l /lib/cpp
lrwxrwxrwx 1 root root 53 Nov 21 1999 /lib/cpp ->
../usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/cpp*

So, can someone please explain to me why the 7.0.3-1 package complains
that /lib/cpp isn't there when it is? FWIW, I got the same error when I
tried using the --force switch with rpm. Something's screwy here.

Thanks,

Rich
