I'm sorry for jumping in late, but maybe you
installed and mixed files, binaries, and libraries
for all your GCC stuff?

I always check for gcc version like this;

$ gcc --version


Here is what I've done in my case. KURT and DAVID
BANDEL, Andrew Mathews, and Net Llama pointed me in
the right direction, although it took awhile to for
me comprehend and understand their advice.  ;)



I wanted to upgrade the compilers, be able to quickly
dump them when necessary, but still retain the
original compiler intact;

installed gcc version 2.95, 3.1, 3.2, 3.2.2  in the
following manner;

/usr/local/share/gcc/<version_number>/

When I built all my installation files for the compiler,
I placed them all under that particular directory, so say for
instance 2.95.3, which I learned was the wrong thing to
do, but it worked...It makes deleting them very easy now,
since I merely dump that particular directory.

So, for instance, 2.95.3 looked like and had all the
compiler files in the following locations.

/usr/local/share/gcc/2.95.3/bin
/usr/local/share/gcc/2.95.3/lib
/usr/local/share/gcc/2.95.3/include
/usr/local/share/gcc/2.95.3/info
/usr/local/share/gcc/2.95.3/man
/usr/local/share/gcc/2.95.3/i686-pc-linux

Then I edited my /etc/.bashrc file for the root
account, and then add a export for the particular
compiler I want to use.  I merely had to specify the
/bin directory of that particular compiler.

When I tried the first time, I was using the
Caldera 3.1.1 distro, and the compiler I wanted
to use was for all users, so I copied and saved,
then changed the /etc/.bashrc file to
something like this...

You may want to save and then alter your root .bashrc file,
and have a statment order that specify the compiler you
wish to use first, pointing to that particular binary.
[ typically, /usr/local/bin  ]


What my setup looked like, what I did.


The Original /etc/.bashrc statement;
<tab> means insert tab here...


# try to generate an elaborate PATH ...
_p="$HOME/bin"
[ "$UID" = 0 ]<tab>&& _p="$_p /usr/local/bin /sbin /usr/sbin"



===========

My modified /etc/.bashrc statement;

I exchange /usr/local/bin for

/usr/local/share/gcc/2.95.3/bin


NOTE:

the last line is all one line...
<tab> means insert tab here...


# try to generate an elaborate PATH ...
_p="$HOME/bin"
[ "$UID" = 0 ]<tab>&& _p="$_p usr/local/share/gcc/2.95.3/bin
/sbin /usr/sbin"



========

Next,

The compiler specific included libraries.
I had to include them for the particular compiler.
I had to modify the /etc/ld.so.conf file to see them,
so I had to edit that file.

The original /etc/ld.so.conf;

/usr/X11R6/lib
/opt/kde/lib
/opt/kde2/lib
/usr/lib/qt2/lib


The modified version of /etc/ld.so.conf;

/usr/X11R6/lib
/opt/kde/lib
/opt/kde2/lib
/usr/lib/qt2/lib
/usr/local/share/gcc/2.95.3/lib
/usr/local/share/gcc/2.95.3/lib/gcc-lib/i686-pc-linux/2.95.3/


Then load the cache, as root,

$ ldconfig -v

I confirm the cache contents by doing this...

$ ldconfig -p

Done.

====

I have yet to figure out how to reload the current
libraries loaded on boot up by Linux.  If I knew, it
would be a matter of simply stopping and restarted or
rather, reloading the libraries required.

I was stuck with rebooting the computer, but
since I was the only user, it didn't matter.


HTH.
